In this Article, we'll explore how to deploy a Strands Agent connected to an MCP server using serverless AWS services. We'll cover three deployment models—Lambda (native & web adapter) and Fargate—and compare their pros, limitations, and recommended scenarios. Strands Agents SDK provides a convenient model-driven loop, while MCP enables dynamic tool invocation. Deploying them on AWS serverless platforms allows you to build scalable, maintainable agents without managing servers1. Option Benefits Limitations AWS Lambda (Native) Fast startup, easy CI/CD, unified observability Max 15-minute execution, no streaming support2 Lambda with Web Adapter Preserve web frameworks, serverless pay-per-use Slower cold start (1–3 s), added complexity3 AWS Fargate (ECS/EKS) Long-running containe…  ( 5 min )

I've been thinking a lot about org charts lately. Not because I love them (I don't), but because I recently started at Lattice after spending years working on AI startups, and getting onboarded into the HR world has me reflecting on what the future of work might actually look like. What's struck me isn't the technology itself, but how we're still thinking about AI within the constraints of traditional organizational structures. We debate whether AI will replace people or empower them, but we're not really asking how AI might impact organizational design itself - how it could reshape people's roles within companies. A few weeks ago, I was on a bike ride around the UW campus in Seattle with my partner when she made an observation that really stuck with me. She predicted that undergrad progra…  ( 7 min )

1. Introduction Hey, fellow coders! In today’s data-hungry world, web crawlers are the unsung heroes powering everything from price trackers to sentiment analysis. But here’s the catch: when you’re scraping millions of pages, a single-machine crawler feels like drinking from a firehose with a straw—slow and frustrating. Enter distributed web crawlers: a squad of machines working together to conquer the web at scale. This guide is for devs with a year or two of Go under their belts—folks who vibe with goroutines and HTTP requests. We’re building a distributed crawler from scratch in Go, tackling real-world challenges like IP bans and goroutine leaks. Why Go? It’s the Swiss Army knife of languages: lightweight concurrency, killer networking, and dead-simple deployment. By the end, you’ll h…  ( 8 min )

Introduction Hello everyone! Today, I am going to share with you all what I recently found and how good it is. Recently, I came to know about an Asset Management Platform that helps developers like us manage assets on the web efficiently. Yes! I am talking about Cloudinary (an Image and Video API Platform). It provides dynamic APIs to manipulate assets like images and videos on the web. But today, I am not going to share what Cloudinary is; instead, we are going to explore some new and exciting features from Cloudinary. A quick introduction to Cloudinary for those who haven't heard this name before, so you can understand the blog better. If you already know what it is and have used it, you can skip this section. Cloudinary is an Image and Video API Platform that offers dynamic APIs to ho…  ( 5 min )

I am the kind of developer who hates to install things and likes to use online quick tools for my daily small dev tasks. I recently found myself frustrated (again) with the usual dev utilities online: slow, ad-heavy, sketchy data leaks, and zero consistency. Every time I needed something as simple as a YAML validator or regex tester, it felt like stepping into a time warp of old-school websites with painful UX. I had enough, So I decided to do something about it and build something better. And this time, I do it in public. No tracking or spying: Everything runs in browser. No user data is ever sent to server or anyone. Zero latency: Instant results = no loading bars, no waiting. Secure & portable: Works offline or behind firewalls. Perfect for corporate private environments or company setu…  ( 4 min )

Introduction Using resilience patterns like @Retryable and @CircuitBreaker are often seen as a best practice. But when you mix Retry with a Circuit Breaker without fully understanding how they work together, your application may behave in ways you never intended. This isn't just about avoiding errors; it's about avoiding silent failures. This post is about what happens after you implement both, and what you need to configure to ensure your app is resilient without losing control over logic. When using Spring Retry alone: @Retryable( retryFor = { SocketTimeoutException.class, TemporaryServiceException.class }, maxAttempts = 3, backoff = @Backoff(delay = 1000) ) public String fetchData() { return externalApi.call(); } If all 3 retry attempts fail, the final exception is th…  ( 5 min )

If you’ve ever had to set up billing for a SaaS app, you already know the feeling: you're knee-deep in Stripe’s dashboard, juggling webhooks, syncing subscription data, and somehow duct-taping everything together with your auth and RBAC system. It's doable. But elegant? Not really. Kinde assumes something different: you’re building a product — and billing should just work. Imagine if your billing worked like an identity, with pricing, access, and authentication all living in one place? That’s exactly what Kinde Billing is trying to solve. It's a new layer on top of Kinde’s already well-regarded auth platform — and while still early, it’s built with one clear goal: making billing feel native to the product you’re building. I am using it to power Learnflow AI (an AI voice tutor tool I’m work…  ( 7 min )

Hey everyone, It’s called modcore Extension Manager — it’s a browser extension that helps you manage your other extensions. Now it has: Automation rules (like: disable some extensions on certain sites, or only turn them on at certain times) A better view into what extensions are actually doing Search, grouping, quick toggles — just things that make dealing with a bunch of extensions less of a mess It’s not on the Chrome Web Store yet, so if you want to try it, it has to be installed manually from GitHub: https://github.com/modcoretech/modcore-extension-manager I’m mostly just curious if this is something others would find useful, or if it’s just me going too far trying to organize my digital chaos.

Picture this... You’re building your first real app. The MVP is finally working. Users are signing up. Your early testers are hyped. Then your team lead hits you with: “Hey, can you add billing before Friday?” You smile, nod, open a new tab… and immediately regret your life choices. Stripe is awesome — don’t get me wrong — but if you’ve tried implementing it raw, especially when you don’t have a lot of time, then you know the pain: Multiple docs to go through. Webhooks that break when left unmanaged. You’re wiring up pricing tables, syncing subscription states, building a billing UI and a customer portal… all from scratch. You copy a price ID into the wrong .env file and suddenly nobody can upgrade to Pro anymore. It’s like you’re working with IKEA parts, but half the instructions are m…  ( 8 min )

A number of personal commitments meant I had to take a break from the course, so I am just trying to get back on track now, albeit very slowly. I am currently working on the Binary Search Tree (have reached the delete method implementation (not yet finished). I (again) struggled with how to set variables within a function that uses recursion without causing an infinite loop. In spite of having taken an extended break, it actually clicked with me that I could just pass those variables as parameters and set their values within the parameters themselves.

Automating software testing is a no-brainer for quality analysts, testers, and software developers. While taking the code-full route for testing is highly embraced among the testing community, this track has its own share of impediments. It definitely gives you that added flexibility to bend the test scenarios and factors for more appropriate results. However, indulging in such a method may often cost a handsome investment in terms of both resources and time. This is where codeless or no-code automation testing has risen to fame among the software testing fraternity and small businesses investing in software or application development. This method can render a quicker turnaround and better ROI. However, you can only cover limited or fewer conditions when compared to coded automation. No-co…  ( 6 min )

On July 20, 2025, Khoj Samachar, a grassroots digital news platform from Nepal, was ranked 45th globally by The Org—a global directory known for mapping transparent and verified media organizations. This inclusion placed it alongside institutions like The Economist, The Washington Post, and HarperCollins. But unlike these giants, Khoj Samachar began with no newsroom or corporate backing—just a borrowed camera and a mission to report from earthquake-hit Sindhupalchok. Founded by investigative journalist Roshan Shrestha, the platform evolved through field-based reporting, civic stories, and digital tools. Today, it reaches thousands through its app and social channels—amplifying underreported issues in and beyond Nepal. This recognition underscores a shift: global visibility no longer depends on scale, but on substance. 📎 Read full post  ( 3 min )

If you’ve ever tried searching for files on Windows, you know the pain. Get-ChildItem crawls on large directories. Tools like Everything are fast, but they’re GUI-first—not ideal when you need something scriptable and automation-friendly. I wanted a lightning-fast, command-line tool for Windows that just works. So I built rq: an open-source file search utility written in modern C17, optimized for speed and simplicity. Speed: Typically 3–7x faster than common alternatives like Get-ChildItem Parallel directory traversal: Built on the Windows Thread Pool API Flexible search: Supports glob, regex, and hidden files Powerful filters: Size, extension, date, file type Automation-friendly: Streams results as plain text or JSON 🔍 Example Usage # Find all C/C++ source files rq C:\Dev "*.c" --glob --ext c,h # Search for large images rq D:\Photos beach --ext jpg,png --size +500K # Export recent documents as JSON rq C:\Users\me\Documents report --ext pdf,docx --after 2025-01-01 --json Building rq wasn’t just about speed—it was about handling the quirks of Windows: Long paths & Unicode: rq uses \\?\ paths and UTF-8 internally Thread pools over raw threads: Better scalability and resource control Minimal syscalls in hot paths: Avoid unnecessary overhead for performance Custom directory traversal logic: Fully parallel with dynamic work distribution C17 is still fantastic for high-performance, low-overhead tools Windows APIs are powerful but tricky—path handling and Unicode are a minefield Thread pools > raw threads for stability and performance Avoid syscalls in tight loops for real speed gains rq is open source (MIT) on GitHub: https://github.com/seeyebe/rq If you use Windows and need a fast, scriptable file search, give it a try!

How to Install Git and Create a Bare Repository? Anusha Kuppili ・ Jul 20 #git #devops #dataenthusiastera #vcs  ( 3 min )

When you're working in a DevOps team, one of the first things you'll often be asked to do is set up a Git repository for developers to collaborate on code. In this short guide, we’ll walk through how to do exactly that—install Git and create a bare Git repository on a Linux-based Storage Server. A bare repository is a Git repository that doesn’t have a working directory. That means you can’t directly edit or work with files there. It’s mainly used as a centralized remote repository that teams push to and pull from. Perfect for collaboration and production environments. Most Linux servers, especially RHEL or CentOS-based ones, don’t have Git pre-installed. To install Git using yum, simply run: sudo yum install git -y This will install Git and its dependencies silently without prompting for confirmation thanks to the -y flag. Once Git is installed, it's time to create the actual repository. The requirement is to create a bare repository named /opt/official.git. Here’s how to do that: sudo git init --bare /opt/official.git The --bare flag tells Git to create a repository meant solely for sharing—not for editing files directly. The path /opt/official.git is exactly what the team requested, so make sure it matches. ✅ Installed Git with yum ✅ Created a centralized bare repo at /opt/official.git You’ve now set up a clean, professional remote Git repository that your dev team can start using for collaboration right away. Happy DevOps’ing!  ( 4 min )

AWS SQS also known as Amazon Simple Queue Service now started supporting IPv6 on VPC endpoints via AWS PrivateLink. Thus it enables Private, Secure and Cost-Optimized message queuing Services Benefits Previously, IPv6 supports on AWS was limited to public endpoints. But now it's extended to all VPC endpoints across all AWS Regions! One of the goal is to make the people change from IPv4 to IPv6 because IPv4 is a 32bit address it supports approximately 4.3 billion users. Which is filling faster due to increase use of internet by users but IPv6 is 128 bit address which support roughly 340 undecillion addresses. So, to faster the transition from IPv4 to IPv6 AWS already came up with a scheme of charging for public IPv4 address but using of public IPv6 address is free in AWS. The cost rate is costs $0.005 per hour, or $43.80 per year which increases the cloud charges of companies. By extending there support to IPv6 and also not stopping the support for Ipv4, Amazon Web Services (AWS) makes the transition from IPv4 to IPv6 seamless—no need to flip everything at once.

In everyday development, some functions may need to receive a large number of parameters, some of which are required, while others are optional. When there are too many parameters, the function becomes bulky and hard to understand. Additionally, if new parameters need to be added in the future, the function signature must be modified, which will affect the existing calling code. The functional options pattern solves this issue. In Go, the functional options pattern is an elegant design pattern used to handle optional parameters in functions. It provides a flexible way to allow users to pass a set of optional parameters when calling a function, rather than relying on a fixed number and order of parameters. Ease of Use: Callers can selectively set function parameters without needing to remem…  ( 6 min )

How to Talk to an AI 💻: A Beginner’s Guide to the OpenAI API Akemnoor Singh ・ Jul 20 #ai #openai #programming #webdev  ( 2 min )

Ever wondered how apps talk to ChatGPT? Let’s break down the simple but powerful way you can chat with models like GPT-4. LLM : A Large Language Model is an algorithm that uses training data to recognize patterns and make predictions or decisions We’ve all been amazed by what LLMs can do. But what if you want to build that magic into your own website or application? The answer is that you can use OpenAI APIs. An API is just a way for different software programs to talk to each other. In this case, it lets our app have a conversation with OpenAI’s powerful models. Each request to the API consists mainly of a LLM model name an array of messages (basically an array of objects) Other optional settings Let’s Write Some Code! First, you need the official OpenAI library. Then, you set up the clie…  ( 4 min )

In our earlier deep dive into Direct Memory Access (DMA), we explored how data can bypass the CPU to move efficiently between storage and memory. Traditional (Buffered) I/O Memory-Mapped Files Direct I/O When you run something like: int fd = open("data.txt", O_RDONLY); read(fd, buf, 4096); // read 4096 bytes from fd into buf Page Cache Lookup → The OS first checks its page cache, a large shared memory pool used to avoid redundant disk access. This cache holds recently accessed file data from all processes. Read-Ahead → If the OS needs to fetch data from disk, it doesn’t just fetch the 4 KB block you asked for. It reads ahead, often 32 KB or more, anticipating sequential access patterns. We will use this information later in the article against Traditional IO (and mmap too). Double Copy →…  ( 5 min )

In our journey so far, we've deployed an application, configured it with ConfigMaps and Secrets, and exposed it to the world. Our application is configurable and accessible. But it has a fatal flaw: it is stateless. The Nginx container we're running doesn't need to save any data. But what if we were running a database, a blog, or a user profile service? By default, the filesystem inside a container is ephemeral. When a Pod crashes or is restarted, it's replaced with a brand new one with a fresh, empty filesystem. Any data saved in the old Pod is gone forever. This is a dealbreaker for almost any real-world application. To solve this, Kubernetes has a powerful storage model that allows data to live independently from the lifecycle of a Pod. To untangle the complexities of storage, Kubernete…  ( 7 min )

1. Introduction Modern web applications demand high performance, fast load times, and seamless interactivity. Traditional React apps, while powerful, often struggle with performance bottlenecks due to hydration costs, large JavaScript bundles, and heavy client-side logic. As applications grow, these issues become more pronounced, leading to slower time-to-interactive and increased resource usage on users' devices. Frameworks like Next.js have evolved to address these challenges, introducing server-side rendering (SSR), static site generation (SSG), and incremental static regeneration (ISR). However, these solutions still require shipping significant JavaScript to the client and hydrating components after the initial HTML is loaded. React Server Components (RSC) represent the next logical…  ( 7 min )

1. Introduction Cascading Style Sheets (CSS) is the language that brings the web to life visually. Since its introduction in the late 1990s, CSS has been foundational for web design, enabling developers to separate content from presentation and create visually engaging, responsive experiences. Over the decades, CSS has evolved dramatically, from simple color and font changes to complex layouts and utility-first paradigms. This article traces the journey of CSS: from the early days of float-based hacks, through the rise of frameworks like Bootstrap, to the modern era of Tailwind and utility-first design. Along the way, we’ll see real code examples from each era, understand the motivations behind each shift, and learn when to use (or avoid) the latest tools. By the end, you’ll have a deep…  ( 7 min )

After 24 years as a software consultant and game developer, watching the 2025 tech market has been eye-opening... Despite shipping 40+ production applications, building experiences for 10M+ users, and achieving 300% performance improvements at IBM-scale, I'm still navigating the same ATS black boxes and arbitrary coding challenges as everyone else. My Unreal Engine expertise and real-time 3D skills seem invisible to resume scanners looking for exact keyword matches. The rise of AI is creating an interesting paradox - while I'm integrating LLMs and AI tools into client solutions, there's a perception that seasoned developers are becoming redundant. Yet someone still needs to architect these systems, ensure they scale, and fix them when they hallucinate. The emotional toll is real. After successfully running a consultancy since 2000, serving Fortune 500s and government agencies, each form rejection stings. It's surreal getting "not enough experience" responses when you've literally trained entire teams at some of the biggest name companies out there. To my fellow senior devs and specialists - we've solved harder problems than this. We've migrated from Flash to WebGPU, from monoliths to microservices, from 5-day processes to 4-hour solutions. This job market is just another system to debug. The challenge is especially acute when you're supporting a family and have skills that don't fit neatly into "React Developer" or "Backend Engineer" boxes. Being an expert in game engines, full-stack, AND AI apparently makes you harder to categorize, not more valuable. Here's the deal: the industry desperately needs big-picture thinkers, the kind of folks who can connect the dots between our nostalgic past and our sci-fi future. Hang in there, champions. Stay Weird. Phil  ( 3 min )

Когато сте въвеждали текст на български език ползвайки кирилска клавиатурна подредба като БДС или фонетична, то навярно сте забелязали, че с тези подредби не може да се въвеждат някои символи като квадратни и къдрави скоби ([] и {}). Разбира се това не е пречка да се ползват кирилските клавиатурни подредби. Неудобство е обаче, ако искате да програмирате на ДжаваСкрипт ползвайки подобна подредба. Някои биха отбелязали, че не само липсата на квадратни и къдрави скоби би представлявала трудност да се програмира на ДжаваСкрипт ползвайки Кирилица.

Hey Devs 👋 If you're diving into cybersecurity, you’ve probably run into this: Countless blog posts. I’ve been there. As a computer science student, I was obsessed with learning pentesting, bug bounty hunting, and malware analysis. But finding good, structured content was chaotic. So I fixed that for myself — and now I’m sharing it with you. 📦 What’s Inside the CyberSec Vault? Here’s what you get: ✅ Top GitHub Repositories ✅ Premium Cybersecurity Courses ✅ Categorized YouTube Channels ✅ Must-Read Articles & Websites 🧠 Why I Made It (and Why It's $4) The $4 cost helps me: Offset the time spent curating (yes, hours) It’s a tiny investment — but it could save you weeks of wasted time. 🚀 Get It Now CyberSec - Vault  ( 3 min )

Hola comunidad, Hace unos días tuve la oportunidad de participar como speaker en el AWS Community Day Panamá 2025, donde presenté sobre CloudFormation Hooks.

I scored 825/1000 on my AWS SAA-C03 exam — but only after falling face-first into every trap AWS could throw at me. Here’s how to avoid the mistakes that nearly cost me my certification. The Trap: You think an ALLOW policy grants access, but a hidden DENY in another policy nukes it. The Fix: Imagine DENY is Thanos — it snaps ALLOW out of existence. The Trap: Mixing up stateful (Security Groups) and stateless (NACLs) rules. The Fix: NACLs are like airport security — check everyone in and out. The Trap: Enabling versioning, then realizing you can’t disable it — only suspend it. The Fix: Use versioning only for critical data. Need to “disable”? Start fresh with a new bucket. S3 versioning is like tattoos: easy to add, impossible to remove fully. The Trap: Using a CNAME for example.com (instead of www.example.com). The Fix: ALIAS records for apex domains. CNAME only for subdomains. CNAMEs can’t be used at the zone apex; you must use ALIAS or A records. CNAMEs at the apex are like using a phone charger as a Wi-Fi antenna — it just doesn’t work that way. The Trap: Using Multi-AZ for read scaling (spoiler: it’s for failover only). The Fix: Multi-AZ is for survival — failover and resilience. The Trap: Using CloudWatch for API audits (it’s for app logs). The Fix: CloudTrail: Who deleted my S3 bucket? (API tracking). The Trap: Running mission-critical apps on Spot Instances (they can vanish mid-task). The Fix: Spot instances should be used for: Batch processing Stateless workloads Non-urgent tasks Spot Instances are like tinder dates: cheap, fun, but don’t expect commitment. The Trap: Spending 4–6 minutes on one question. The Fix: Answer easy questions first (2 mins each) and flag the rest. If you’re not sure and need to take a guess, try to eliminate one or two wrong answers before making a choice. Once you eliminate the wrong ones, look for word differences between the remaining options. One of them will make more sense than the rest :)  ( 4 min )

In the ever-evolving world of cybersecurity, the old myth that certain operating systems are "immune" to viruses is not just outdated—it's dangerous. Modern threats are increasingly built to be versatile, adaptable, and platform-agnostic. Few threats illustrate this new reality better than Chaos RAT, a potent, open-source Remote Access Trojan (RAT) that poses a significant and ongoing threat to both Windows and Linux users. Written in the powerful Go programming language, Chaos RAT began its life as a legitimate open-source tool. However, its powerful features, ease of use, and public availability have made it a favorite among cybercriminals. It represents a democratization of cybercrime, where sophisticated tools are no longer the exclusive domain of elite hacking groups. This comprehensive guide will break down everything you need to know about this threat: its origins, its technical advantages, its malicious capabilities, and most importantly, the definitive steps you must take to protect your systems. The journey of Chaos RAT began not in a clandestine dark web forum, but in plain sight on GitHub, where it was published as a remote administration tool by its creator. The project includes a standard disclaimer absolving the developer of liability for misuse—a common feature of "dual-use" tools. While not created with malicious intent, its architecture, featuring a powerful command set and remarkable ease of deployment, made it an ideal candidate for weaponization. Around late 2022, security researchers began observing Chaos RAT in malicious campaigns, primarily targeting Linux servers and cloud instances to deploy cryptocurrency miners. This pivot from a public project to a malicious tool highlights a major trend: cybercriminals are increasingly leveraging open-source software to build effective and low-cost malware.

When working on a project, you might make several changes before you commit. However, these changes might relate to different features or bug fixes. For example, you might change a file to fix a bug, but you might see something else in the file that bugs you, so you fix it while you're there. Committing all changes at once can lead to a messy, hard-to-understand commit history or a more complex code review process. Git lets you selectively stage parts of your changes instead of adding the whole file. Using this feature, you'll get a cleaner history with smaller units of work for peers to review, as well as a chance to deal with any out-of-scope work you still want to keep but commit elsewhere. In this tutorial, you'll explore this feature by creating a small HTML project and staging your c…  ( 6 min )

If you're working on a project in the CLI and you've navigated to a subfolder, you might want a quick way to navigate back to the project root. You can use a combination of pushd and popd to jump around your shell, but there's a faster way if your project is a Git repository. Git installed on your machine. The command git rev-parse --show-toplevel will tell you the path to the top-level directory of a repository. You can feed the result of that command to the cd command to jump to that folder: $ cd $(git rev-parse --show-toplevel) That command is way too long to remember, so create an alias for it. With the Bash shell, add an alias by adding the following line to ~/.bashrc on Linux or ~/.bash_profile on macOS: alias cdr='cd $(git rev-parse --show-toplevel)' If you use zsh, add the alias to ~/.zshrc. When you open a new terminal window or source your configuration file, you can use the command cdr to jump to the project root. When working in a large monorepo with subprojects, like sample code for a book or course, this is a huge time saver.  ( 3 min )

Swift Package Manager (SwiftPM) has evolved significantly since its inception, becoming the de facto dependency management solution for Swift projects. With the acceptance of SE-0482, SwiftPM now supports binary static library dependencies on non-Apple platforms, marking a crucial milestone in Swift's journey as a truly cross-platform language. This enhancement addresses long-standing limitations that prevented developers from distributing precompiled libraries for Linux, Windows, and other non-Apple platforms through SwiftPM.

Hey friends, Exactly one year ago, Mattia and I started building a small idea on the side. We didn’t have a team. We didn’t have an audience. Just an itch — and the belief that Threads would need its own ecosystem of tools. Today, BlackTwist just passed $1.5k MRR. It’s still early. But it feels real. So I wanted to share a few things from behind the scenes — not just the wins, but the messy parts too. We started from scratch. Zero followers. Zero traffic. Zero hype. Our only “unfair advantage” was that we had been power users of Twitter/X schedulers for years. So when Threads launched, I knew exactly what I wanted as a creator — and no one had built it yet. So we did. I handled the tech. Mattia handled the marketing. At least… that’s what we tried to do. The reality is: we both love buildi…  ( 4 min )

Empowering Large Language Models with External Knowledge ⸻ 🚀 Introduction Large Language Models (LLMs) like GPT-4, Claude, or LLaMA have taken the world by storm, generating code, emails, reports, and insights with ease. But here’s the catch — they’re trained on a fixed dataset and can’t access fresh, dynamic, or private data on their own. This is where Retrieval-Augmented Generation (RAG) comes in — a game-changing architecture that combines retrieval-based search with generative AI to produce more accurate, context-aware, and up-to-date responses. ⸻ 🧠 The Problem with Static LLMs Even the most powerful LLMs face these limitations: RAG solves this by allowing the LLM to retrieve external context just before generating an answer. ⸻ ⚙️ *What is Retrieval-Augmented Generation (RAG)? RAG is an AI architecture that enhances LLM performance by integrating real-time or relevant document retrieval into the prompt. 🧩 RAG = Retrieval + Generation ⸻ 🖼️ Simple RAG Workflow User Query → Embed Query → Search Vector DB → Retrieve Top N Docs 🛠️ Tools That Use or Support RAG ⸻ 💡 Real-World Use Cases ⸻ ✅ Benefits of RAG ⸻ ⚠️ Challenges to Consider ⸻ 🧠 Final Thoughts RAG is one of the most powerful patterns in the GenAI world today — giving your LLMs the ability to reason with fresh, relevant, and proprietary data in real-time. If you’re building AI copilots, search engines, smart chatbots, or anything that needs context-aware responses, RAG is the foundation you should start with. ⸻ 👇 Have questions or want to see a RAG demo?

🤔 Why This Matters If you're working with data at any scale — engineering, analytics, AI, or product — you need to understand how systems handle transactions versus analytics. Many architectural decisions hinge on this: what data to collect, how to store it, and how to process it. In this post, we’ll break down OLTP and OLAP — their purposes, patterns, and when to use each. OLTP stands for Online Transaction Processing. Purpose: Real-time transactional operations (e.g., purchases, inserts, updates). Workload: High volume of small, fast reads and writes. Common in: Web apps, banking systems, e-commerce platforms. Design Focus: Fast inserts and updates High availability Low latency Data normalization Customer checkout on an e-commerce site Banking withdrawal or deposit Creating a user a…  ( 4 min )

AI-powered search is evolving fast. But you don’t have to wait for the big players—you can build your own Deep Search AI that pulls fresh results from the web (DuckDuckGo) and then asks powerful LLMs via OpenRouter to read, summarize, and refine them into human-friendly answers. 🔥 In this article, I’ll walk you through the full build: from fetching raw search data, to refining it with AI, to wiring up a simple web UI. Let’s go! 🚀 A Deep Search AI pipeline does more than show links. It: 🔍 Fetches raw results from a search source (DuckDuckGo Instant Answer API). 🧵 Extracts key snippets (titles, summaries, related topics, abstracts). 🤖 Feeds that corpus into an AI model (via OpenRouter) to analyze. 🧾 Returns a concise, well-structured answer—optionally with cited sources.

This week wasn’t about shipping products — it was more about slowing down, figuring things out, and being honest with myself. I was mostly burnt out. No ideas, no motivation to code, just stuck. Despite that, I landed a freelance gig. Haven’t been paid yet, but it technically marks my first bit of income during Hustle2Grand. I tried validating two small SaaS ideas: A paid directory of the dumbest coding bugs that wasted devs' time A service that generates SaaS names with .com domains still available Neither idea got any real traction or payments. I realised a big part of the burnout came from setting goals I couldn’t control — like “make money this week.” That led to disappointment when things didn’t land. So I’ve shifted my mindset: I want to build software to solve problems, not just to earn money My weekly goals should be focused on things I can control, like finishing an MVP or launching a feature If money comes, great. But it shouldn’t be the only outcome I care about One of the problems I’ve been facing personally is that I don’t drink enough water. So I’m building an app to help with that. It’s still early — I’ve just started brainstorming — but it feels good to be building something based on a real problem I care about solving. Also, I’ve decided I want to try mobile app development in general. This app will be my first proper attempt at it. No big promises — just going to keep showing up, building cool stuff, and sharing the journey. If you’re stuck or feeling burnt out, try shifting the goal. It helped me. And as always, if you want to try Hustle2Grand yourself: hustle2grand.vercel.app  ( 4 min )

Inspired by the sleek UI of Windows, I built a mock Windows Settings Page using pure HTML, CSS, and JavaScript. The goal was to practice modular code separation and basic JavaScript logic like dynamic filtering. This project simulates how the Windows settings interface works — allowing you to search for a setting and immediately see matching options. Here’s how I did it 👇 🧱 Technologies Used HTML (Structure) CSS (Styling & Layout) JavaScript (Search Functionality) ⚙️ Features: ✅ Responsive cards for settings (Device, Network, Privacy, etc.) ✅ Functional search box ✅ JavaScript filters settings dynamically ✅ All settings reappear once the search input is cleared 💡 What I Learned: How to structure a project using separate files (HTML, CSS, JS) How to use JavaScript to dynamically show/hide elements based on input How important it is to organize image paths and project folders. Window UI I’m still improving this layout, and would love your feedback! Let me know how I can improve the UX/UI or add more interactive elements.

You know that feeling? You open your editor, type a few words... and in seconds, Copilot completes the entire code. Claude, Gemini CLI, Cursor, Windsurf—all ready to refactor your function like magic. It's impressive. And, to be honest, a little scary too. Fundamentals: Understand What's Happening Before asking AI to "create a function that searches for users," try writing a loop yourself. If you don't know the difference between a for...of and a forEach, or when you really need to use async/await, you'll have trouble debugging that "perfect" code the AI generated. What doesn't work: Blindly trusting the tool. Asking AI to "avoid excessive API calls" might generate functional code, but it might not be ideal for your specific case. What works: Understanding the why behind things. Knowing ho…  ( 7 min )

*A hard look at effort-based pricing and the hidden cost of being a paying beta tester Let me be crystal clear from the start: I've cancelled my Replit subscription, and I won't be coming back. Not for the $10 credit they're dangling like a carrot, not for the promises of "improved pricing transparency," and certainly not to continue being an unwitting contributor to their model training while paying premium prices for the privilege. This isn't just about money. It's about respect, fairness, and the fundamental question of who benefits when paying customers become unpaid quality assurance testers for AI systems that will ultimately compete against us. When Michele Catasta, Replit's President & Head of AI, posted their explanation for the pricing model change, he mentioned they've been "r…  ( 8 min )

Introduction "I am familiarizing myself a bit with Power BI. I was looking for a fun dataset. I like Formula 1. I searched and found it. 14 CSV files all with a different table schema. Of course, I used Chat GPT. I asked how I could do this automatically. I got an answer, but I still had to create a query 14 times. You can also read and import Excel files. I first made a PowerShell script with Chat GPT. It works fine, but the script was not very fast. I wrote the script in Python, and it is significantly faster. Perhaps if you read this, you wonder why I am sharing this? I completely understand. But by thinking that you can export it to Excel yourself and I can't find much about it on the internet. I decided to share it anyway. It can save a lot of time. Maybe you can find it on the internet. But I am not good at searching." import pandas as pd import glob import os from tqdm import tqdm # Configuration csv_folder = r'f:/archiveF1' # folder with your .csv files excel_output = r'F:/samengevoegdv2.xlsx' # output file # Retrieve all CSV files csv_files = glob.glob(os.path.join(csv_folder, '*.csv')) # Write to a single Excel file, each CSV on a separate sheet with pd.ExcelWriter(excel_output, engine='xlsxwriter') as writer: for file in tqdm(csv_files, desc='CSV to Excel', unit='file'): sheet_name = os.path.splitext(os.path.basename(file)) df = pd.read_csv(file, delimiter=',') df.to_excel(writer, sheet_name=sheet_name, index=False) print(f'Done: all {len(csv_files)} CSVs have been imported into {excel_output}') You can fine-tune the script a bit more with ChatGPT, for example by having it create the Excel file, with or without a specific naming convention. ChatGPT handled everything here. Maybe you are smarter and would have chosen Excel right away. I didn’t, and once again, that’s why I’m sharing this.  ( 4 min )

Are you ready to create your first backend project with Node.js? In this post, you’ll learn how to build a basic Node.js HTTP server that handles different routes and sends back responses — all using core Node modules (no frameworks like Express yet!). Let’s break it down step by step and explain exactly what’s happening behind the scenes. 💡 Before writing any code, we need a place to put it: mkdir my-nodejs-server cd my-nodejs-server npm init -y This creates a new project folder and initializes it with a default package.json file. Now let’s create the file that will run your server: touch server.js Open server.js in your code editor (VS Code, Vim, or anything else you like). const http = require('http'); 👉 This brings in Node.js’s built-in http module, which lets us create web server…  ( 5 min )

What Is an Ultrasonic Sensor? An ultrasonic sensor is a distance-measuring device that uses sound waves to detect how far an object is without physical contact. It emits ultrasonic waves, waits for them to bounce back from an object, and calculates the distance based on the time it takes for the echo to return. The HC-SR04 ultrasonic sensor is one of the most popular and budget-friendly sensors for measuring distance in electronics and robotics projects. It provides accurate, non-contact distance measurement from 2 cm to 400 cm, making it ideal for: The HC-SR04 sensor works using sound wave reflection: 1️⃣ The Trigger Pin sends a short ultrasonic pulse (40 kHz).

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, CSS Art: Office Culture. The developer life isn’t always about polished UIs and pixel-perfect components. It's the late-night coffee sips, whiteboards covered in ideas, and that one browser tab with a stubborn error. Note: For the best experience, view this in a desktop browser at 100% zoom. The layout is handcrafted and may distort on other scales. Live Preview Source Code This project began as a blank canvas, quite literally. No JavaScript, no libraries. Just raw HTML and CSS. My goal was to express what it's like to be a developer, not just build something for one. From the skewed books we swear we’ll finish... To the error tab sitting right next to our editor... To the blinking cursor and cozy desk lights... Every detail was crafted manually using nested divs, shadows, transforms, and pure CSS creativity. Inspired by VS Code’s dark UI and the vibe of late-night hacking, I played with gradients, layering, and subtle hover effects to simulate depth and personality. CSS-only animations (like blinking cursors) skew() and translate() to give perspective Dark mode palettes inspired by GitHub and macOS Terminal Manual color picking to create warm lighting and shadows Mimicking real UI elements with pure CSS What I’m proud of most is staying within the boundaries (no JS!) while still conveying a scene that feels lived-in, cozy, and familiar to every dev.

Not too long ago, computers were obedient but limited machines. They could only do exactly what they were told—nothing more, nothing less. Every function, every response, every possibility had to be programmed manually by a developer. If you wanted a computer to play chess, you had to write code that accounted for every possible move, strategy, and outcome. These machines were smart—but only as smart as the people who coded them. But then, something remarkable happened. Machine Learning came into the picture. It was a paradigm shift. Instead of programming a computer to follow instructions, what if we could teach it to learn from experience—just like humans do?

This blog is part of a series. Getting the program to compile and run is a challenge. Getting it to run correctly is even more of a challenge. You would want to know exactly what the program is doing, and how it's different from what you intended for it to do. This is known as debugging. Debugging takes place at various stages of a program's lifecycle, starting from the programming stage. There are various linters and scanners that go over your source code and identify undesireable functionality. Most of them are intended for use from your editor-turned-IDE, such as VIm. As an example, for the programs ctags and cscope, here's a video. After programming and compilation, you get a binary program image, which you can also analyse. Analysis at both source code and binary image stages is calle…  ( 7 min )

Streamlining Development with Image to React Tools Accelerating UI Creation with Image to React Conversion Let's be real, hand-coding React components from UI designs can be a drag. It's time-consuming and prone to errors. But what if you could just upload an image of your design and have it automatically converted into React code? That's the promise of image-to-React tools. These tools analyze your UI images and generate the corresponding React components, saving you a ton of development time. Think about it: no more painstakingly recreating designs pixel by pixel. Instead, you can focus on the logic and functionality of your application. This is especially useful for rapid prototyping or when you need to quickly iterate on UI changes.

This is the default and most familiar pattern. You deploy a smart contract to a Near account by sending a transaction with the DeployContract action, which includes the compiled WebAssembly code. The contract is deployed to the same account from which the transaction was sent. For example, deploying to contract.testnet means the code now lives and run…  ( 6 min )

As .NET developers, we’ve all done this: var client = new HttpClient(); It’s easy, it works… until your app starts failing unexpectedly due to port exhaustion. Why creating multiple HttpClientinstances is dangerous How IHttpClientFactorysolves the problem How to structure your code using Clean Architecture ❌ The Problem with new HttpClient() Bad practice: creating HttpClient for every request public async Task GetWeatherAsync() { using var client = new HttpClient(); var response = await client.GetAsync("https://api.weather.com/forecast"); return await response.Content.ReadAsStringAsync(); } Why is this bad? new HttpClient() opens a fresh TCP connection. When used frequently (e.g., in loops or heavy API calls), this leads to port exhaustion, causing your HTTP requests to fail. IHttpClientFactory .NET introduced IHttpClientFactoryto manage reusable and efficient HttpClientinstances. public interface IWeatherService { Task GetForecastAsync(); } public class WeatherService : IWeatherService { private readonly HttpClient _httpClient; public WeatherService(HttpClient httpClient) { _httpClient = httpClient; } public async Task GetForecastAsync() { var response = await _httpClient.GetAsync("/forecast"); response.EnsureSuccessStatusCode(); return await response.Content.ReadAsStringAsync(); } } builder.Services.AddHttpClient(client => { client.BaseAddress = new Uri("https://api.weather.com"); client.DefaultRequestHeaders.Add("Accept", "application/json"); }); With IHttpClientFactory, .NET reuses connections under the hood, improves performance, and avoids port exhaustion.

One of the most overlooked yet foundational stages in building a successful software product is the iteration phase that raw, unglamorous stretch where you sit down with your first 10 to 50 users and truly listen. Before even thinking of scaling, advertising, or acquiring thousands of users, this is where great products are forged. Not in boardrooms or pitch decks, but in deep conversations with early users. It’s in these moments when you’re not trying to sell but trying to learn that you uncover what really matters. What’s confusing? This is how you find out if your product is solving the right problem, or if you’re just building features in a vacuum. And it’s how your earliest users go from passive testers to active evangelists because they see you listening and building in real time. Ov…  ( 4 min )

I'm excited to be speaking about this topic at OpenSSF Community Day India, and wanted to share some insights on this fascinating intersection of chaos engineering and security. When most people hear "chaos engineering," they immediately think of Netflix's famous Chaos Monkey randomly terminating servers to test system resilience. But what if we took that same philosophy and applied it to security? What if, instead of waiting for attackers to find our vulnerabilities, we intentionally broke our own systems to discover weaknesses first? Welcome to Security Chaos Engineering – a practice that's transforming how we think about proactive security testing. Let's start with some uncomfortable truths about modern security: 277 days - that's the average time it takes to detect a security breach(ac…  ( 8 min )

When your Flutter app grows beyond a few screens and features, your codebase starts to feel like a jungle. You find business logic inside widgets, API calls scattered across UI files, and trying to test anything becomes a nightmare. Sound familiar? This is where Layered Architecture comes in and not just for the sake of organization, but for maintainability, scalability, and testability. Let’s break this down from core principles to real-world implementation with no fluff. At its core, layered architecture separates your app’s responsibilities into distinct layers. Each layer focuses on a specific role and communicates only with its adjacent layers. Here’s the classic 3+1 layered structure in a Flutter context: Presentation Layer Application Layer (Use Cases) Domain Layer (Business Rules) …  ( 5 min )

What is PCI DSS? The Payment Card Industry Data Security Standard (PCI DSS) is a global set of security requirements designed to ensure that all companies that process, store, or transmit credit card information maintain a secure environment. While often discussed in the context of systems handling cardholder data (CHD), its requirements extend to the storage infrastructure, including Solid State Drives (SSDs), where CHD might reside. PCI DSS primarily addresses Secure Sockets Layer (SSL) and its successor Transport Layer Security (TLS) in the context of data transmission over networks. While SSDs themselves don't directly use SSL/TLS protocols (these are network protocols), the systems accessing or sending data to/from SSDs often do. Here's where SSL/TLS becomes critical for PCI complia…  ( 5 min )

The First Whisper of Vibe Coding Not by “I” — but by the one who *saw it before it had a name.* “Sometimes you don’t create a revolution. Before the movement. There was someone else. Not a coder. Just a quiet soul in the comment section of a forgotten repo. They weren’t loud. But their comment… changed everything. “This doesn’t feel like code. That was it. A small, passing phrase. “Coding Without Syntax: A Broken Experiment.” you uploaded, expecting no one to notice. But someone noticed.

TL;DR — Got tired of wasting time on long YouTube videos, built my own summarizer, put it online. I kept running into the same problem. I’d open a YouTube tutorial, hoping to learn something quick… I’m a developer — I like figuring things out on my own. I looked around for tools that could summarize YouTube videos or generate YouTube transcripts. So at some point, I figured… why not just build something myself? That’s how LinaGPT came to life. It’s nothing fancy. No logins. No paywalls. I didn’t build it thinking it would become some big SaaS product. Maybe this could help a few other people too. So I put it online. If you’ve ever felt stuck watching endless YouTube videos and wished you could just grab the key points or download the YouTube transcript, LinaGPT a try. Or not. I just figured I’d share this little project I built — maybe it saves someone else a bit of time. That’s the fun part of working in tech, right? Thanks for reading.  ( 4 min )

Sup, framework fans! 🛠️ We've analyzed real-world sites in Part 16 of our The Power of HTML series. Now, in Part 17, we're bridging HTML with modern frameworks like React, Vue, and others—showing how HTML remains the core even in component-based worlds. JSX in React or templates in Vue are essentially HTML supercharged with JS logic, enabling reusable UIs without losing markup's essence. In 2025, frameworks dominate, but HTML's semantics and structure keep things accessible and performant. We'll touch AI frameworks too, like Vercel AI SDK for dynamic content. Tools like ChatGPT (go-to for generating component code) or Grok (top-notch for refining with AI integrations) make experimentation quick.

I would really like to play with some LLMs locally, because it will allow to better understand the nuances of their work. It’s like getting acquainted with AWS without having dealt with at least VirtualBox before — working with the AWS Console or AWS API will not give an understanding of what is happening under the hood. In addition, the local model is free, and it will allow tweaking the models for ourselves, and in general, try out models for which there are no public Web or API services. So I will try to run it on my gaming PC. There are many ways to do this: Ollama: easy to use, provides an API, it is possible to connect the UI through third-party utilities like Open WebUI or LlaMA-Factory API: yes UI: no llama.cpp: very lightweight — can run even on weak CPUs, includes only CLI and/or…  ( 11 min )

We have an automation for AWS IAM that creates EKS Access Entries to give AWS IAM Users access to an EKS cluster. I don’t remember if I wrote it myself or if some LLM generated it (although judging by the code, I did :-) ), but later I discovered an unpleasant feature of how this automation works: when a user is deleted from variables, Terraform starts “re-mapping” other users. Actually, today we’ll look at how I did it, recall Terraform’s data types, and see how that should have been done it to avoid such problems. Although the error is described about aws_eks_access_entry resource (here in the examples it will be local_file instead of aws_eks_access_entry), it actually concerns the general approach to using indexes and loops in Terraform. Current implementation Variables and data types v…  ( 11 min )

After migration to a new EKS cluster, we started getting alerts about 503 errors sometimes. The errors were happened in three cases: sometimes without any deployment, when all Pods were Running && Ready sometimes during deployment — but only on Dev, because there is only one Pod for API and sometimes during Karpenter Consolidation. Let’s dig into the possible reasons. A little context: our setup ALB and EKS: 502 vs 503 vs 504 Possible causes of 503 Issue #1: different keep-alive timeouts ALB idle timeout 600 seconds, Backend — 75 seconds Where did the 600 seconds on Ingress come from?

Managing multiple vendor dependencies has become a critical challenge for modern businesses. When your operations rely on dozens of third-party services, tracking their status individually becomes inefficient and risky. A status page aggregator solves this problem by consolidating all vendor status information into a single dashboard. Most companies depend on 20-50 external services for their daily operations. These include cloud providers, payment processors, communication tools, analytics platforms, and API services. Each vendor typically maintains its own status page, creating several challenges: Information overload: Checking 30+ status pages manually is time-consuming and prone to human error Delayed incident detection: Critical outages can go unnoticed for hours without centralized m…  ( 7 min )

Everyone says 2025 is the year of AI agents. The headlines are everywhere: "Autonomous AI will transform work," "Agents are the next frontier," "The future is agentic."

Introduction Ever tried using a shadcn/ui Button as a link while also including icons or other JSX inside? If so, you may have hit a frustrating issue: the styles break, or worse, your icon ends up outside the clickable area. In this article, you'll learn why that happens—and how to fix it. asChild The Button component from Shadcn supports an asChild prop, which swaps the rendered button element for something else (like a Link or a tag). Under the hood, it uses @radix-ui/react-slot's Slot component to forward props and styles to the element. Here’s a typical Button implementation: //components/ui/button.tsx function Button({ className, variant, size, asChild = false, ...props }: React.ComponentProps & VariantProps & { asChild?: boolean;…  ( 4 min )

Introduction Have you ever interacted with an AI agent that asked you for missing details before it could help—like clarifying what you meant or asking follow-up questions? That process is called elicitation. Elicitation is how AI agents gather the right pieces of information from you, step by step, in order to complete a task. Instead of needing everything upfront, the agent engages in a back-and-forth conversation—filling in gaps, confirming choices, and adjusting as needed. It’s what makes modern AI feel interactive, guided, and helpful. Now imagine this process extended across multiple turns in a conversation that’s multi-turn elicitation. Rather than overwhelming users with all the questions at once, multi-turn elicitation allows AI agents to ask for one piece of information at a t…  ( 7 min )

If you're managing Linux servers in any capacity — production, staging, or internal — you need to ask yourself one thing: Why is root allowed to SSH in directly? Here’s the thing: direct root login over SSH is a security risk that’s just not worth it. It gives attackers a straight shot at the most powerful user on your system. That's why one of the first things I do when hardening servers is disable it. Let’s break down how to do that cleanly and safely. ❗Why This Matters Brute-force bots love targeting the root account No accountability (you can’t tell who logged in) One password = total compromise By disabling root login: You force users to authenticate with their own accounts You get better visibility via sudo logs You reduce your SSH attack surface by a mile ✅ How To Disable Root SSH Login SSH into your server as a non-root user: ssh your_user@your_server Open the SSH config file: sudo vi /etc/ssh/sshd_config Find this line: #PermitRootLogin yes Uncomment and change it to: PermitRootLogin no Save and exit, then restart SSH: sudo systemctl restart sshd Double-check it’s applied: sudo grep -i PermitRootLogin /etc/ssh/sshd_config PermitRootLogin no 🧠 Good To Know For larger environments, automate this with tools like Ansible or Terraform. You can take it a step further by disabling password login entirely and switching to key-based auth. 🚀 Wrapping Up If you haven’t done this yet — now’s the time.  ( 4 min )

As developers working at the intersection of Web3 and AI, we all recognize the increasing tension between performance and privacy. Most AI pipelines today require massive amounts of data, but provide little to no guarantees on how that data is used or protected. Users surrender control in exchange for convenience, while centralized entities reap the rewards. The Oasis Network proposes a radically different architecture for AI model training: one where data contributors retain sovereignty, logic remains private, and incentives can be baked in through smart contracts. The key component? Sapphire — Oasis’s confidential EVM runtime. Sapphire allows developers to write Solidity contracts that execute in trusted execution environments (TEEs). That means both data and model logic can be kept confidential, even during execution. This unlocks use cases like: Training models on sensitive datasets (healthcare, finance, user behavior) without leaking raw inputs. Running on-chain AI inference without exposing proprietary models. Designing systems where data contributors are compensated in a verifiable, trustless manner. Through the Oasis DeAI framework, you can architect decentralized training pipelines where every party—data provider, model developer, and end-user—interacts through smart contracts with embedded privacy guarantees. It’s still early, but if you’re building AI tools that need user data while respecting user control, this is a technical path worth exploring. You can dig deeper here. Happy to discuss implementation details or explore architectural patterns for privacy-preserving AI if others are building in this space.  ( 3 min )

When it comes to tracing the Linux kernel, kprobes and kretprobes are some of the oldest and most flexible tools in the eBPF ecosystem. In fact, kprobes were introduced long before eBPF, first appearing in Linux kernel 2.6.9 (2004), enabling dynamic tracing of almost any kernel function without requiring kernel recompilation. eBPF came later (around kernel 3.15+) and builds upon kprobes by allowing users to attach safe, sandboxed, and highly programmable code to kernel functions, including kprobes and kretprobes. This combination provides a powerful foundation for modern observability and performance tooling. While kprobes and kretprobes typically have higher overhead compared to other eBPF program types like XDP or tracepoints, their versatility makes them invaluable. They can attach to v…  ( 7 min )

Understanding useEffect in React “Why do I need it?” “When does it run?” “What is it even doing?” In this blog post, I’ll explain what useEffect is, how it works, and show you examples using a simple React app. What is useEffect? Fetching data from an API Updating the DOM manually Starting or cleaning up timers Subscribing to services (e.g., websockets) Think of useEffect as "do something after the component appears or updates." Basic Syntax import { useEffect } from 'react'; useEffect(() => { The second argument is a dependency array — it controls when the effect runs. Example 1: Logging on Component Mount function Hello() { return Hello, useEffect! ; } Example 2: Fetching Data with useEffect import React, { useState, useEffect } from 'react'; function UserList() { useEffect(() => { https://jsonplaceholder.typicode.com/users") return ( User List {user.name} Example 3: Cleanup Function useEffect(() => { return () => { Explanation: Conclusion It may seem tricky at first, but once you understand the dependency array and when effects run, it becomes much easier to manage.

So, I’ve launched my first SaaS (FounderSignal) and honestly it feels a bit wild, like standing on a brand new basketball court with nobody around to play. really start. I spent weeks (okay, months) building stuff nobody actually wanted before. This time? I flipped the script. Instead of hoping for the best, I tried to get feedback before writing a single line of code. A few things that surprised me: Most founders (including me) are afraid to ask strangers if the idea stinks. When I finally did, the feedback wasn’t as harsh as I imagined, most people actually wanted to help. Early feedback saved me from chasing “nice to have” features. FounderSignal is my way to help other builders who don’t want to gamble months for a “maybe.” The thing I wish I had last year: quick, real feedback from real humans. If you’re building anything (SaaS, side project, new app), skip the guesswork. Share your idea early, test it before you build, and talk to people who’d actually use it. I’d love to swap stories or hear your own “startup fails” (the real, embarrassing ones). Let’s help each other out so fewer ideas die quietly in someone’s downloads folder.

Building a Mini DBaaS with Kubernetes: A DBA's Cloud-Native Engineering Journey Why Did I Build This? As a Database Administrator (DBA), I've always been curious about how cloud database services like AWS RDS work internally.

One of the most common tasks in programming is swapping the values of two variables. Traditionally, this requires using a temporary variable like this: let a = 1; let b = 2; let temp = a; a = b; b = temp; console.log(a, b); // 2 1 While this works just fine, JavaScript (ES6 and later) offers a much cleaner and more concise solution using array destructuring. With destructuring, you can swap two variables in just one elegant line: let a = 1; let b = 2; [a, b] = [b, a]; console.log(a, b); // 2 1 On the right side, [b, a] creates a new array with the values in reversed order. On the left side, [a, b] destructures that array and assigns the values back to the original variables. This means the value of a becomes the old b, and the value of b becomes the old a. No need for a temporary variable → cleaner memory usage. More readable and concise → easier for other developers to understand your code. Great for real-time logic like sorting, toggling, or UI logic (e.g., flipping values in animations). Let’s say you're implementing a basic sorting algorithm and you want to swap two items in an array: if (arr[i] > arr[i + 1]) { [arr[i], arr[i + 1]] = [arr[i + 1], arr[i]]; } Simple, readable, and highly effective. Using array destructuring to swap variable values is a smart JavaScript trick that every modern developer should have in their toolkit. It’s clean, fast, and makes your code much more elegant.

At Pleenk, like in most projects I’ve worked on, the number of tests inevitably grows over time — and with it, the execution time. As feedback loops get longer, developers lose effectiveness, and eventually motivation to test. That’s when issues start to creep in. One common way to maintain fast feedback is to prioritize unit tests. They are great for testing individual components in isolation and for exploring edge cases. But they’re not enough. Nothing gives me as much confidence as a good integration test — one that verifies that components work correctly together in a real configuration. This is the story of a developer trying to reconcile confidence and speed, to write effective integration tests and ease the pressure on an overloaded CI pipeline.

As a Beginner, the word Vim might sound scary in the tech world, but hey, I am here to rescue. Below is the quick guide for navigating the scary Vim world. Let's get started. Creating our first file using Vim * Go to your Bash terminal and run the command below to create a newfile vim newfile.txt It will open an interface like this Vim has different modes, with Normal mode and Insert mode being the most important. Normal mode is used for navigation and commands, while Insert mode is used for editing text. Let's see how we can switch between different modes- You can press i key on your keyboard to go into the Insert mode where we can edit the text. To return to Normal mode, we can click the Esc key. So, previously we have created the file newtext.txt, now we are going to edit the file. i key (yes, on your keyboard) to enter the Insert mode. Enter the text you want that file to contain. You can use the arrow keys (↑ ↓ ← →) to move around the editor. If you are not able to edit the text, check if you are in Insert mode by looking at the bottom of your editor. After entering the text, we got to save the file. Press the Esc key to return to the Normal mode. When you are in Normal mode, type the :w command in your editor to save the file. Lastly, we need to exit our Vim environment, type the :q command to exit. If you want to save and quit the editor, just type :wq or :x, and if you want to quit without saving, you can type :q! in Normal Mode. Dealing with Git commit message with the following steps Press i to ensure you are in Insert mode and enter the commit message. Then, press the Esc key to make sure you are in Normal mode. Type :wq and press Enter to save the message and exit. If you want to abort the merge, type :ql! then Enter. Command Table So this is a quick way to create, edit, navigate, save, and exit the almighty Vim. Hope this guide helps you.  ( 4 min )

1. Why We Migrated We maintain a large, multi-entrypoint Single Page Application (SPA) with a custom router and integrated micro-frontends via Module Federation.

JavaScript, as a versatile and widely-used programming language, often sparks debates about its fundamental concepts. One such topic is whether JavaScript truly has primitive data types. In this article, we aim to clarify this question, exploring the nature of JavaScript's data types and providing a definitive answer. In programming, data types define the kind of values a variable can hold and the operations that can be performed on them. JavaScript divides its data types into two major categories: primitive types (like numbers and strings) and objects (often referred to as reference types, since they are passed by reference), which include arrays, functions, and more complex structures.

In today’s world, technology often gravitates toward unnecessary complexity, with bloated software and intricate systems like AI dominating development. I believe we should prioritize simpler methods that empower humans, avoiding overcomplication that can lead to inefficiency, loss of control, and even economic disruption. Most of us view technology as computers or electronics, but even a chair, glasses, and the stairs we climb are technologies that aim to address human needs. Several years ago, during a hiking trip, I had a fascinating conversation with an engineer about the fax (facsimile). While fax machines are often mocked, their underlying technology offers a powerful lesson in designing simple, human-centered tools. In 1846, Alexander Bain invented a chemical device that reproduced…  ( 5 min )

UTL_FILE – Practical Guide | mrcaption49 This implementation demonstrates an end-to-end CSV export process in Oracle using UTL_FILE. First, two relational tables—emp_department and employee—are created to simulate HR data. Sample records are inserted into both tables. A procedure export_employee_csv is then defined to build a CLOB string by first adding a CSV header and then appending employee details by joining the tables. This CLOB is passed to a helper procedure generate_csv, which efficiently writes the CLOB content to a physical .csv file using chunked writes via UTL_FILE. The chunking ensures large data volumes are handled safely. A dedicated Oracle Directory (NGCSUTL) is created and granted access, pointing to an OS path for file export. When export_employee_csv is executed, it ge…  ( 5 min )

Artificial intelligence didn't just appear overnight. It was built on decades of mathematical discovery, scientific experimentation, and technological iteration. In this article, we’ll trace the timeline of AI from its theoretical foundations in the 1940s to the explosive progress of models like GPT-4. This blog is your scientific and historical roadmap to becoming an AI-savvy thinker. The seeds of AI were planted when Alan Turing introduced the idea that machines could simulate reasoning using binary symbols (0s and 1s). Shortly after, McCulloch and Pitts designed the first artificial neuron—an idea so fundamental that it’s still embedded in every neural network today. These early abstractions laid the groundwork for what would become modern-day deep learning. Turing also proposed a novel…  ( 4 min )

Welcome to Day 7 of 15 Days of Tailwind Tips As you continue building with Tailwind CSS, you’ll quickly notice patterns forming in your code — repeated classes for buttons, cards, inputs, and more. Repetition isn't necessarily bad, but it can make your markup harder to maintain. This is where the @apply directive comes in. Tailwind gives you the flexibility of utility classes in your HTML, but also provides @apply to consolidate styles into reusable custom classes when needed — especially helpful in larger projects or component libraries. Let’s walk through how @apply works and how to use it effectively. @apply The @apply directive is used inside your CSS (or PostCSS) to include Tailwind utility classes into a custom class.

This blog was originally posted on the Docker official website Generative AI (GenAI) is revolutionizing software development, but creating AI-powered applications comes with significant challenges. First, the current AI landscape is fragmented — developers must piece together various libraries, frameworks, and platforms that weren’t designed to work together. Second, running large language models efficiently requires specialized hardware configurations that vary across platforms, while AI model execution remains disconnected from standard container workflows. This forces teams to maintain separate environments for their application code and AI models. Third, without standardized methods for storing, versioning, and serving models, development teams struggle with inconsistent deployment practices. Meanwhile, relying on cloud-based AI services creates financial strain through unpredictable costs that scale with usage. Additionally, sending data to external AI services introduces privacy and security risks, especially for applications handling sensitive information. These challenges combine to create a frustrating developer experience that hinders experimentation and slows innovation precisely when businesses need to accelerate their AI adoption. Docker Model Runner addresses these pain points by providing a streamlined solution for running AI models locally, right within your existing Docker workflow. In this guide, we’ll build a comprehensive GenAI application that showcases how to create a fully-featured chat interface powered by Docker Model Runner, complete with advanced observability tools(Prometheus, Grafana and Jaeger) to monitor and optimize your AI models.

Service Mesh: Solving On-Premises Kubernetes Networking When you're managing your own Kubernetes cluster on-premises, you have unmatched control—but also full responsibility for everything, especially networking. In modern microservices architectures, this responsibility is magnified by the sheer volume and complexity of service-to-service communication. Kubernetes networking is commonly divided into: North-South Traffic: Flows between the outside world and your cluster. Managed by Ingress Controllers. East-West Traffic: Internal service-to-service communication within the cluster. This is where service meshes excel. Distribution between these traffic types in a typical microservices setup emphasizes just how critical managing east-west traffic is: Distribution of Kubernetes Traffic: No…  ( 4 min )

1. So what is AWS Strands Agents SDK? AWS Strands Agents SDK is an open-source, lightweight Python framework for building AI agents. It adopts a model-first philosophy—minimizing scaffolding and eliminating verbose prompting by trusting modern LLMs to drive planning, reasoning, and tool execution[^1]. It enables developers to build agents rapidly, scaling from simple prototypes to production deployments on AWS[^2]. Why it Matters: Instead of manually specifying workflows and logic, Strands lets the LLM interpret tasks, select tools, and determine execution paths. This model-first strategy rethinks traditional agent design by entrusting the model with reasoning capabilities[^3]. The SDK is designed to be minimal and flexible—free from rigid frameworks or complex prompt templates. The arch…  ( 5 min )

When we talk about how modern applications are built, one term shows up over and over: microservices. The idea might sound like a trendy buzzword, but it’s actually a fundamental architectural approach that powers everything from Instagram to Netflix to Pinterest. Microservices are a way to structure your backend into independently deployable, small, and focused services. Each one is responsible for a specific business function, and each runs in its own process. They communicate with each other using lightweight mechanisms—often HTTP APIs, message queues, or event streams. That’s the textbook answer. Let’s make it real. Imagine you're building Pinterest.

Part 1: What is State? And Why Should I Care? When you're building an interactive app with React, you want your components to remember stuff. But React doesn’t just magically remember things like: Whether a button was clicked What the user typed into a field If a modal is open or closed That’s where state comes in. 🤔 What Is “State”? 📦 It’s like a mini storage unit inside your component — and when you change what’s inside, React updates the UI automatically! 🧠 Real-World Analogy: Mood Ring If you're sad, it turns blue If you're excited, it glows purple_ Your mood is the state — it changes based on how you're feeling, and the ring (UI) reacts to it. 🧩 Enter useState() import React, { useState } from 'react'; function MoodRing() { const [mood, setMood] = useState('😊'); return ( Your mood: {mood} setMood('😢')}>Sad setMood('😄')}>Happy ); } 👀 What’s Happening Here? const [mood, setMood] = useState('😊'); You're telling React: "Hey, I need a piece of memory called mood" "Set it initially to 😊" "Give me a function setMood to change it" When setMood is called, React updates the value of mood Re-renders the component with the new mood 🧪 Beginner Tip: Always Use setState You shouldn’t modify state variables directly: mood = '😡'; // ❌ Wrong! setMood('😡'); // ✅ Correct! Why? Because React won’t know something changed unless you use the setter function (setMood). That’s how React knows it needs to update the UI. 📌 Coming Up in Part 2...

This task involves several variables: encapsulation, coupling, cohesion, performance, reusability, and flexibility. At the center of all this is a concept that, although rarely directly discussed, has a profound impact on the quality of the architecture: granularity. Granularity, in the context of object-oriented programming, represents the level of division or fragmentation of a system into its components — especially classes and objects. It's like deciding whether a class should do many things or just one…  ( 5 min )

I have gotten so tired of spending 2-3 hours setting up the same stack for every new Next.js project. Database, auth, state management, forms - it's always the same dance. To simplify that, I created nextjs-starter-pack — a one-command CLI to generate a fully configured, modern Next.js 15 apps with customizable integrations. Every developer has that folder of "reference projects" they copy configs from. I realized I was basically rebuilding the same foundation over and over, just with slight variations depending on the project needs. The breaking point was starting my fourth SaaS project and realizing I was about to spend another afternoon wiring up Clerk auth with Prisma... again. Instead of copying code, why not generate it? Try it with: npx nextjs-starter-pack Or explore the full range of options: npx nextjs-starter-pack --help Foundation: Next.js 15 + React 19 + TypeScript + Tailwind + Shadcn/ui Database: Prisma or Drizzle Auth: Auth.js or Clerk State: Zustand or Jotai Plus: TanStack Query • React Hook Form + Zod • Dark mode If you're tired of the setup ceremony that comes with every new Next.js project, give nextjs-starter-pack a try. It might just save you an hour on your next project. Links: GitHub Repository NPM Package I'd love to hear your feedback or feature requests. Feel free to open an issue on GitHub or reach out directly. I'm actively working on new integrations (Stripe, i18n, CI/CD workflows, analytics, PWA, etc.) to make this the go-to for creating Next.js apps, and if any open sourcers are interested in helping build this, feel free to reach out on Reddit. Stop setting up. Start building.  ( 3 min )

Projetar um sistema orientado a objetos vai muito além de simplesmente criar classes e distribuir métodos. Uma das decisões mais difíceis e também mais cruciais está em como quebrar o sistema em partes menores, ou seja, como decompor o domínio em objetos e responsabilidades bem definidas. Essa tarefa envolve diversas variáveis: encapsulamento, acoplamento, coesão, performance, reusabilidade e flexibilidade. No centro disso tudo está um conceito que, embora pouco discutido diretamente, tem um impacto profundo na qualidade da arquitetura: granularidade. Granularidade, no contexto da programação orientada a objetos, representa o nível de divisão ou fragmentação de um sistema em seus componentes — especialmente em classes e objetos. É como decidir se uma classe deve fazer várias coisas ou uma …  ( 5 min )

“Error handling in Go is too verbose to write.” — This is a sentiment almost every Go programmer agrees with. Recently, the Go team published an official blog post, formally announcing: they will no longer pursue any new proposals for error-handling syntax. This means that, moving forward, when writing Go code, you'll still be frequently typing the familiar line: if err != nil { return err }. This isn’t just the end of a syntactic sugar proposal — it’s a reaffirmation of the entire philosophy behind the language. So why did the Go team make this decision? And how should we interpret their persistence? Over the past seven years, the Go team has tried three times to address the problem of “repetitive error handling” by introducing new syntax mechanisms. None of these efforts made it to adopt…  ( 8 min )

Stellar may be setting up more upside after XRP's recent price surge, US President Donald Trump signed one of the first bills related to crypto, and other news.

The line between a central bank digital currency and a centrally-managed, government-regulated stablecoin is thin, critics argue.

The decline of the US dollar and the loss of purchasing power due to fiat currency inflation will drive global demand for Bitcoin.

The cybersecurity exploit occurred due to a "sophisticated server breach," CoinDCX CEO and co-founder Sumit Gupta announced on Saturday.

The FHFA directive on crypto in mortgage risk assessments risks excluding self-custodied assets, potentially increasing counterparty risk for homebuyers.

Multiple chart technicals and indicators suggest that XRP price has the potential to stage a parabolic rally over the next few weeks.

Spot Bitcoin ETFs have attracted over $6.6 billion in 12 days, boosting assets under management to $152.4 billion.

Crypto Week in the US ends with some victories for the crypto lobby, with the GENIUS Act headed to Trump’s desk.

A fake hardware wallet bought via TikTok led to a $6.9-million crypto theft; hackers are now targeting devices meant to keep funds safe.

Ether is punishing shorts already, but another 10% ETH price upside will liquidate $1 billion, helping cement $4,000 in the process.

Charles Schwab plans to offer spot trading for Bitcoin and Ethereum, aiming to attract clients who want to consolidate crypto holdings with their traditional assets.

Cayman Islands-based Bullish has filed for IPO registration with the SEC, aiming to list on NYSE as “BLSH.”

Block’s inclusion in the S&P 500 comes just two months after crypto exchange Coinbase made history as the first cryptocurrency firm to join the index.

Galaxy Digital’s Michael Harvey says the most optimistic scenario for Bitcoin is a “continued slow melt-up” through the end of July.

Bitcoiner Peter McCormack says the police "have failed" the town of Bedford and insists he can do a better job by deploying his own security team.

Introduction In my previous blog post, I introduced the concept of Vibe Coding. It is one of the new ways that is attracting even non-programmers. Users can describe their thoughts using natural language and AI tools would convert that into a working application. Spotting this opportunity, I thought I should experiment and understand what that actually looks like in action. I took this opportunity to test out a few tools and see how they really impact my workflow. It is not just about automating tasks; it is about changing our behaviour on how to approach a problem. To me, it feels like a declarative approach, especially when you are navigating a new framework or language for the first time.

It doesn’t matter where you went to law school, how many cases you’ve won, or how high your GPA was. If you work in the legal field long enough, there’s a good chance you’ll hear a little voice in your head whisper, “You don’t belong here.” That’s imposter syndrome. And the worst part is, it doesn’t usually show up when you’re failing, it shows up right when you’re doing well. You land the job, win the motion, get praise from a partner, and instead of celebrating, you think, I just got lucky. They’re going to figure me out. The truth? You’re not alone. Some of the most capable, high-achieving attorneys deal with the same doubts. Why? Because law rewards perfectionism, constant comparison, and pressure to always know the answer. It’s easy to feel like you’re falling short when the bar is constantly moving. But here’s the thing: imposter syndrome isn’t telling the truth. The fact that you care that you question yourself, that you want to be better, that’s not a flaw. That’s what makes you a thoughtful, ethical professional. The problem isn’t that you don’t know enough. It’s that you’ve convinced yourself that everyone else knows everything. One of the best ways to quiet that voice is to talk about it. Chances are the people you admire most have felt the same way. Keep track of your wins, your progress, and the times you figured something out you didn’t think you could. And remember, confidence doesn’t come from pretending to know everything—it comes from knowing you’ll figure it out, even when you don’t. You earned your seat at the table. Don’t let a lie in your head make you shrink from it. Created By: Dalton A. Breshears  ( 3 min )

Hume AI's EVI 3: The Dawn of Hyper-Realistic Voice Cloning In the rapidly evolving landscape of artificial intelligence, Hume AI has just thrown down a significant gauntlet with the launch of its third-generation Empathic Voice Interface, EVI 3. While previous iterations of voice AI have mastered text-to-speech, Hume is pushing the boundaries into the realm of empathic communication. EVI 3 isn't just about generating speech; it's about capturing and replicating the very essence of human expression, a development that promises to redefine our interaction with technology. What sets EVI 3 apart is its groundbreaking capability for advanced voice and speaking style cloning. This goes far beyond simple mimicry of a voice's pitch and timbre. The new model can analyze and reproduce the intricate nuances of a person's speaking style—their cadence, intonation, pauses, and even the subtle emotional inflections that make a voice uniquely human. Essentially, EVI 3 aims to create a true vocal fingerprint, capable of generating new speech in a target style that is virtually indistinguishable from the original speaker. This represents a monumental leap from the often robotic and monotonous AI voices of the past. The implications of this technology are profound and multifaceted. On one hand, the potential for good is immense: from creating ultra-personalized digital assistants that truly understand and reflect user emotion, to enabling new forms of content creation and providing realistic voice restoration for individuals who have lost their ability to speak. However, the launch of such a powerful tool also raises critical ethical questions. The potential for misuse in creating sophisticated deepfakes for misinformation campaigns, fraud, or harassment cannot be ignored. As we stand on the cusp of this new era in voice AI, the conversation must pivot towards establishing robust safeguards and ethical guidelines to ensure this technology serves humanity for the better.  ( 3 min )

For a profession built on deadlines, pressure, and perfectionism, burnout in the legal field isn’t a surprise, it’s almost expected. But just because it’s common doesn’t mean it’s normal. And if you don’t learn to recognize the signs early, burnout has a way of sneaking up and steamrolling everything in its path. You might think burnout looks like a total breakdown, but it usually starts much quieter, chronic fatigue, irritability, zoning out during meetings, or feeling like your work doesn’t matter no matter how hard you push. When you're running on autopilot and dreading every Monday, that’s not just stress. That’s your brain waving a red flag. Law culture doesn’t always make it easy to talk about this stuff. There’s a weird badge of honor in being the one who stays the latest or never says no. But long hours and constant pressure aren’t sustainable, no matter how tough you are. Eventually, your work suffers, your health takes a hit, and your love for the law starts to fade. So, what helps? Start with boundaries, real ones. Set limits on your work hours, even if it’s just turning off email at night. Find a non-law outlet that gives your brain a break. Talk to other attorneys who get it. And if things feel unmanageable, don’t wait, consider therapy, coaching, or speaking to someone in your firm or network. Burnout doesn’t mean you’re in the wrong career, it might just mean you need to practice law differently. The goal isn’t to quit. The goal is to stay in the game without losing yourself along the way. Created by: Dalton A. Breshears  ( 3 min )

"Discipline is showing up, even if you don’t ship." Servus and good evening to Day 13 of building my startup solo — and honestly, not much got done today. I had to work a lot at my current main job, and by the time I got home I was just... drained. I opened the CRM project once. Didn’t even touch anything. Just stared at it for a bit and decided — not tonight. Instead, I’ll spend the rest of the evening reading a book. No code. No stress. Sometimes, that's exactly what you need to keep the fire burning long-term. You won’t be productive every single day — and that’s fine. What matters is consistency, not perfection. Back tomorrow — recharged. Thanks for following along, Jonathan (0xj0n1)  ( 3 min )

I write all my notes at work and also my private notes in Obsidian. I find that it works perfect for my personal workflow and helps me be more organized. When I work on a new project, I like to write out a detailed proposal that highlights a possible plan, any issues that might occur, and any open questions. I find myself copying that text over to Teams so that my colleagues also have access to these notes. But when I copy the markdown that I have written in Obsidian, the formatting is not correctly copied over.

Passing the bar is a huge achievement, but what comes next is just as important: figuring out where you actually belong in the legal world. A lot of new attorneys focus on chasing big salaries or prestige, but here’s something that gets overlooked way too often... your personality. The legal field is incredibly broad. Some roles are high pressure and competitive, like litigation or criminal defense. If you’re naturally assertive, enjoy thinking on your feet, and don’t mind confrontation, you might thrive there. But if you’re more thoughtful, patient, and prefer working behind the scenes, you might feel more at home in transactional work, estate planning, or regulatory law. There’s also a real need for emotionally intelligent lawyers, people who are compassionate, good listeners, and resilient, especially in areas like family law, immigration, and public interest work. These paths may not always come with the highest paychecks, but they can be deeply fulfilling. Stats show that most new lawyers start out in litigation or corporate roles, but a surprising number, about a quarter, end up switching practice areas within just a few years. A lot of that has to do with burnout or realizing their job just doesn’t fit how they naturally think or work. So it’s worth asking yourself: Do you like fast-paced environments, or more predictable workdays? Do you get energy from being around people, or do you prefer quieter, more independent work? Are you drawn to arguing and persuading, or would you rather solve problems and plan ahead? Personality tests like Myers-Briggs or DISC can give you some food for thought, but the most important thing is being honest with yourself about what kind of work will actually make you want to show up every day. At the end of the day, finding the right legal path isn’t about picking the most impressive job title, it’s about knowing who you are and where you’ll thrive. That self-awareness is one of the smartest, and most underrated, legal skills you can develop. Created By: Dalton Breshears  ( 4 min )

When it comes to tool-calling and agentic AI, the internet seems awash with tutorials for Anthropic’s Claude or the latest from OpenAI’s GPTs. But what if you want to ride the (less-documented) Gemini wave? If you’ve searched far and wide for a comprehensive guide on integrating the Model Context Protocol (MCP), Gemini, and modern tool schemas, only to find sparse blog posts tailored for other ecosystems, you’re not alone. This tutorial fills that void, focusing on practical integration of Gemini and Model Context Protocol, from both server and client perspectives. We’ll draw on Node.js with TypeScript, @google/genai for Gemini and schema definition, and @modelcontextprotocol/sdk as our primary toolkit. By the end, you should be able registering tools server-side, and activate them client-…  ( 9 min )

Hey devs 👋 Last week I launched DevSolve — a platform where developers can: Solve real-world coding problems and get paid Upload their pre-built tools/modules and earn from them Devs are helping each other every day on GitHub, Reddit, and chats — but rarely get paid directly. Plus, many of us build small tools, components, or solutions that could be useful to others. So I decided to create a platform where: You can post problems and set a bounty Or solve someone else's issue and earn Or upload reusable code to the Toolbox and earn passively 🚀 Results in first few days 300+ users $17.50 in revenue 13 DAUs First real paid solutions delivered Still super early, but I’m excited to build in public and grow it slowly with real feedback. This is the heart of DevSolve right now. Upload: Auth modules UI kits Payment integrations Code snippets/tools Anything that can save another dev time Set your price. If someone uses it, you earn. If this feels interesting, check it out: 👉 https://www.devsolve.club Feedback, criticism, ideas — all welcome 🙌 Let’s grow this together 🚀  ( 3 min )

Introduction to Event-Driven Architecture In traditional application development, components often directly depend on each other, creating tight coupling that leads to code that's difficult to maintain, test, and extend. As applications grow in complexity, this problem compounds, resulting in spaghetti code that's brittle and resistant to change. Event-driven architecture offers a powerful alternative. Instead of components communicating directly, they communicate through events—notifications that something significant has happened. Components can broadcast events without knowing or caring which other components might be listening. Similarly, listeners can respond to events without knowing which components triggered them. Laravel provides a robust implementation of this pattern through i…  ( 11 min )

In the previous tutorial, we introduced double jump mechanics that were automatically applied to players upon entering the World. In this instalment, we will build upon that foundation by implementing a sprint mechanic, allowing players to move more swiftly for a limited duration. Additionally, we will create a straightforward Heads-Up Display (HUD) to visually monitor the player's sprint stamina, ensuring users can easily keep track of their sprinting capabilities during gameplay. Lets start by openening your Player Logic world in the desktop editor and then open the LocalPlayerController script. First we will define the new property which will contain the information needed to manage the sprint mechanic.

Creating a "calendar table" or "date dimension" is a common task in SQL, especially for reporting, data warehousing, or when you need to perform calculations based on dates that might not exist in your actual data (e.g., finding days with no sales). While a full-fledged calendar table usually contains many attributes (day of week, week number, quarter, holiday flags, etc.), sometimes you just need a simple list of dates for a specific period, like the current month. In this post, we'll explore how to dynamically generate a table containing all dates for the current month across different popular RDBMS dialects: MySQL, PostgreSQL, MS SQL Server, and Oracle. This approach avoids hardcoding dates and ensures your script always works for the current period. Why generate a calendar table? Filli…  ( 7 min )

If you’re new to this space, don’t worry—I’m here to guide you like a friend who’s just a step ahead. Today, we’re diving into Terraform, one of the coolest and most widely used Infrastructure as Code (IaC) tools out there. Big companies like Adobe, Airbnb, and Red Hat rely on Terraform to manage their infrastructure using something called HashiCorp Configuration Language (HCL). Sounds fancy, right? Don’t sweat it—we’ll break it all down! In this blog, we’re going on a beginner-friendly journey. First, we’ll unpack what terms like IaC, HCL, and Terraformactually mean (no jargon overload, I promise). Then, we’ll peek under the hood t…  ( 14 min )

So far, we have a running Nginx web server exposed to the world via a Service. Our application's state is defined declaratively in YAML files. This is a huge step forward. But our application is still naive. In the real world, applications need configuration: database connection strings, API keys, feature flags, tuning parameters. Where does this information go? A common anti-pattern is to hardcode these values directly into the container image. This is a terrible practice for several reasons: Inflexible: A change in the database password requires rebuilding and redeploying the entire container image. Insecure: It bundles sensitive information like API keys with your application code, which might be stored in a less-secure registry. Not Portable: The image is tied to a specific envir…  ( 6 min )

Hi All, I have built a simple app (Smart Summarizer) to convert youtube videos into easily consumable summaries. You can then use the summaries to create linkedin post and share your learnings with the world. Now, this problem can be solved using other approaches as well but I wanted to experiment this and see where it takes me. Would like to get your inputs on the app and understand what works well and what could be done better for making it more attractive for people to use. Why was this built - People spend 20-30 minutes on an average watching YouTube videos. With 400 million YouTube videos created every year (of which 20%+ are educational content or podcasts), it is getting more difficult for people to consume content. Personally, I was facing the below problems - Unable to complete a long video or podcast in one go because of distractions and other priorities Wasted time on videos which were not relevant or good enough Learnings which never got captured or utilized beyond a point Thanks in advance artificial #intelligence #ai #replit #youtube #summarizer  ( 3 min )

Antes de começar é importante saber que o desconforto, a ansiedade e a vergonha são sensações e sentimentos comuns entre pessoas que não costumam chegar até outras para perguntar algo. Tu não está sozinho nessa! Aqui vou descrever 3 práticas que eu venho colocando em prática em eventos ou ambientes de networking nos últimos meses pra não levar as dúvidas pra casa, podem ser fáceis ou mais difíceis pra ti, mas ai me conta nos comentários, fecho? Se tu, assim como eu não tem o costume de falar em ambientes com muitas pessoas, essa é a opção certa pra ti! Se estiver em um desses ambientes é bom que tu tenha um bloco de notas no celular e anote todas as dúvidas e falas do palestrante que as dúvidas se relacionem. Espere até que a palestre acabe, se levante e chame o palestrante pelo nome e pergunta se tem 5min para tirar umas dúvidas. Diga seu nome, apresente a fala do palestrante (contexto) e faça a pergunta. E pronto, se ele não compreender bem, tente trazer uma analogia ou um pouco mais de contexto para que ele compreenda bem o que você pensou. Mas se for o caso de estar em um ambiente reduzido, e precisa conversar diretamente com a pessoa, então: Se tu tem dificuldade em lembrar ou explicar as próprias dúvidas, então essa dica é pra ti! Pegue um aplicativo de bloco de notas ou uma folha de papel para escrever na mão as duvidas que você tiver durante a fala do palestrante. Respire fundo se precisar e então faça a pergunta. Mais comum entre extrovertidos, mas não é um impeditivo pra ti não tentar fazer similar viu? Confesso que ainda estou no processo pra pegar o microfone e fazer a pergunta em multidões, mas aguardar a palestra finalizar para ir até o palestrante vem sendo minha abordagem favorita.

Markdown is everywhere — from README files to blog engines. Yet, most Markdown-to-HTML converters today are either: Too heavy (like Pandoc) Too limited (like VS Code preview) Or simply unsafe (Typora exports HTML without XSS filtering) As someone who needed a fast, embeddable Markdown-to-HTML converter in C#, I couldn't find anything that met all of these goals: ✅ Small and dependency-free ✅ Fully supports advanced Markdown (TOC, footnotes, tables, tasks...) ✅ XSS-safe and robust for user input ✅ Easy to integrate into console, desktop, or web apps So I built it. Instead of building a framework, I created a single-file class you can just drop into your project and use like this: string html = Markdown.ToHtml(mdSource); Done. No NuGet packages. No third-party libs. No surprises. Not only does the converter produce clean HTML5 — it also scans your input for: Common Markdown errors (e.g. unclosed **bold** or *italic*) Suspicious input like or phishing links And appends a styled warning block to the HTML output It’s ideal for batch-processing Markdown or handling user-submitted content. 🔹 Just want to test it? Download the .exe and run: mdoc.exe input.md output.html 🔹 Want to embed or extend it? Just copy the .cs file into your project and you're done.

Have you ever stared at a gemstone? The dazzling array of light, the decomposed spectrum, and the shining inner universe seemingly implied within the crystal lattice—how can something so simple, even rigid and mathematical, be so compelling? I feel we often view structure and beauty, the mechanical and the philosophical, as separate arenas of the world when, almost invariably, they are deeply and inextricably interwoven. It is surprising to me that many of us see software as raw mechanicism when so much of what a successful product is is wrapped up in how people feel about its outcomes. The goals of the system and that of the organization, if any, behind it are secondary to this feeling. I think we have gotten so used to the idea of "Software as a Service" that we have dissociated "service…  ( 5 min )

The SkyFi API provides simple endpoints to verify that the service is up and responding: 𝗣𝗶𝗻𝗴 𝗘𝗻𝗱𝗽𝗼𝗶𝗻𝘁: GET /ping – This requires no parameters except the API key in the header. If the service is running, it returns a JSON with a message (e.g., "message": "pong" or a similar friendly response). 𝗛𝗲𝗮𝗹𝘁𝗵 𝗖𝗵𝗲𝗰𝗸 𝗘𝗻𝗱𝗽𝗼𝗶𝗻𝘁: GET /health_check – This returns a status object (e.g., {"status": "healthy"}) indicating the overall health of the API service. Using these endpoints in a test can quickly confirm connectivity and authentication. For example, you could run: If you receive the expected response (HTTP 200 OK with a message), then your API key is valid and the service is reachable. If you get an error (401 Unauthorized or no response), you may need to check your API key or network connection.  ( 3 min )

Everyone’s chasing AI. I get it — it's flashy. But I’m focused on something else: job security, sustainability, and roles that can’t be automated overnight. Business Intelligence, Compliance, and QA might not sound sexy, but these roles keep businesses from imploding. They’re the quiet backbone of every major org. And guess what? These roles aren’t going away. We’re in a weird moment. AI is replacing junior roles. Layoffs are slamming engineers. But behind the scenes? Companies still need dashboards, clean data, tested systems, and airtight risk compliance. I’m intentionally designing a tech path rooted in stability, autonomy, and long-term value. These roles: Require critical thinking, not constant code Rely on attention to detail, not clout Offer remote/hybrid flexibility Allow individual contributors like me to thrive My pivot is intentional.

After years of working in tech, shipping products for others, and juggling life as a solo developer and mother—I’ve decided to build something of my own. Introducing Elyndra Studios. A cozy, modern, child-friendly software studio built with love, story, and purpose. Elyndra was born from something deeply personal—my love for my daughter, Ruby. It all began back in university when I built a social media safety platform for kids called FamilyNova. One of its characters was Skippy the Ferret—a cheeky little creature who would skip reading the terms and conditions, and kids would have to teach him why that was dangerous.

You know how sometimes people tell you that you're just not able to pull something off? Well, that's exactly what got me thinking about all this. I wanted to see if it was possible to cook up something really nice-looking using only 100 bytes of CSS. I mean, 100 bytes? That's barely enough to write hello world! Yet, I just couldn't shake the idea. It was like a puzzle I had to solve. Could it really be done? So, being the curious type, I went ahead and built a little playground to see. OK, so here's the deal. You start with an empty CSS file. Sounds basic, right? Wrong! You only get 100 bytes to type in. Not lines, bytes! Every key press counts.

“A no-nonsense CLI that automates commits, tags, and version bumps — and finally makes semantic versioning behave like it should.” Automation should automate itself — and versioning shouldn't feel like a tax. You ever forget to tag a Git commit, or bump the version number manually, or mistype something in the changelog? Yeah — me too. That’s why I built commit_gh. It's a Bash-based CLI that: Commits your changes ✅ Tags them semantically ✅ Pushes everything ✅ And verifies it all actually worked ✅ Because I was done losing minutes to versioning drama. brew install raymonepping/commit-gh-cli/commit-gh-cli Then just: commit_gh --bump patch --verify This bumps the version, commits changes, creates a Git tag like v1.2.3, and pushes it to origin/main. —- commit_gh --bump patch --verify Checks if your working tree is clean 🧼 Pulls + rebases from main 🔄 Commits and pushes any changes 📦 Bumps the patch version via .version (or creates one if missing) 🧮 Tags and pushes the new version to Git 🏷️ Verifies everything (branch, tag, version file) ✅ —- 🧰 Why I Built This Because git commit is easy. I wanted: A single command to do it all Safety checks before publishing Homebrew installability for all my CLIs ⸻ ✅ Benefits Semantic versioning baked in Verification mode: --verify Self-healing .version file GitHub tag sync Designed for CI/CD or local use Easily extendable ⸻ 📦 Want to Package Your Own CLI? I wrote this to automate versioning for my own Homebrew-packaged tools like: folder_tree 🗂️ repository_audit 🔍 repository_backup 🛡️ Now commit_gh powers all of them — keeping tags, versions, and changelogs in sync. ⸻ 🤖 TL;DR If you’ve ever run git tag, realized you forgot to bump the version, re-tagged, then force-pushed… this tool is for you. ⸻ Check it out: ⸻ Built for engineers.

If you're a developer wanting to dive into human languages, this article is for you. We'll explore how your experience with programming languages can actually speed up your human language learning game. Coding logic and patterns can make picking up languages way less painful than you think. Whether you're a hardcore coder or just curious, this is your vibe. Programming languages mostly fall into two types: static and dynamic. Understanding this helps you connect programming concepts to human language learning. Static languages force you to declare variable types before you run your code. The compiler does strict checks, so errors pop up early — think of it as strict grammar rules in a language class. Examples: C++, C // C++ example of static typing int age = 25; string name = "Njox"; ` …  ( 5 min )

This agility fosters innovation, reduces complexity, and improves operational efficiency across the board. In a composable architecture, a custom software solution refer…  ( 6 min )

Are you writing product copy like engineering documentation, not sales material? Probably, you are making the three mistakes below: You describe what your product does. Users care about what it does for them. Instead of "Advanced AI-powered analytics dashboard," try "See which customers will churn before they leave." Don't list technical specs. Show the outcome users get. Your features should make users think "I need this." You use words like "optimize," "leverage," and "streamline." Normal people don't talk like that. Say "makes your work faster" instead of "optimizes workflow efficiency." Write like you're explaining to your mom. She's smart, but she's not a developer. Drop the buzzwords. Use simple language. You focus on how cool your product is. Users want their problems solved. Start with their frustration: "Tired of losing customers without knowing why?" Then show your solution. Make it about them, not you. Address their 3 AM worries directly. Stop writing like a manual. Start writing like a human who understands other humans' problems.  ( 3 min )

TanStack Table v8 is a game-changer for data grids in React, but its headless architecture often leaves developers piecing together a complex puzzle. If you've struggled with bridging the gap between isolated examples and a fully-featured table, this demo is for you. Siloed Examples: Official docs show features in isolation, leaving you to figure out the integration. The Integration Maze: How do you make sorting, global filtering, column filtering, and pagination work together seamlessly? The Performance Cliff: Tables that are fast with 100 rows but grind to a halt with 10,000. The Feature Treadmill: Re-implementing critical UI patterns like column management and inline editing from scratch. This project provides the comprehensive, production-ready implementation you've been missing. It's…  ( 4 min )

A backend developer's honest take on building semantic search, RAG systems, and recommendation engines As a Laravel backend developer, I'm comfortable with the usual stack – MySQL databases, Eloquent ORM, Redis for caching. But lately, I've been hearing a lot about "AI" and "vector databases" and wondered what all the fuss was about. So I decided to build four projects to understand how these technologies actually work and how they might fit into the web development world I know. This isn't about replacing Laravel or MySQL – it's about understanding new tools that could complement what we already do well. Here's what I discovered by building these projects from scratch. Let me explain this the way I wish someone had explained it to me. You know how in Laravel, we store data in rows and co…  ( 8 min )

Tuples are like standardized forms where each field has a fixed position and specific meaning. In a user registration form, the first field is always the type (:user), the second is the ID, the third is the name, and the fourth is the email. You can't add extra fields or change the order - the structure is fixed and each position has its well-defined purpose. Think of {:user, 123, "Alice", "alice@example.com"} as a structured record where each position tells a specific part of the story. Once created, tuples keep their size and elements in their exact positions, making them perfect for structured data where order and position matter. In this article, we'll explore how tuples work, when to use them, and the patterns that make them indispensable in Elixir programming. Note: The examples in t…  ( 12 min )

Designing a Database from Barely-There Requirements Like many ideas born in Kathmandu, this one emerged from a tea shop: two of my friends discussed a room-rental app to bridge a market gap for a direct-to-owner platform eliminating brokers, a concept surprisingly absent in Nepal's popular app scene. This was the original brief I received: The initial requirements expressed a desire to build an application, but in terms of actual details, they were almost non-existent. I urged my friends to go a bit deeper into each requirement, but there was no follow-up. So, I took it as a chance to build something realistic, grounded in what I had seen in the real world. The first step was research. The initial document referenced "NoBroker," a popular Indian app. Given that rental practices are si…  ( 5 min )

✨ The Rise of Off Season Kristin Juszczyk (wife of 49ers fullback Kyle Juszczyk) launched her own fashion brand, Off Season, partnering with designer Emma Grede (co‑founder of Skims and Good American). The debut collection—featuring unisex puffer jackets, vests, and long coats—quickly sold out, with the 49ers design among those launching the initial drop of five NFL teams. Off Season's jackets reflect high-quality materials and stylish design, aiming for year-round wear—not just game days. Juszczyk explains: “Champions are built in the off‑season… wear it 365 days of the year.” Stay tuned for more updates as the San Francisco 49ers Jacket continue their journey towards greatness in the NFL. 🌟 Cultural Impact The momentum traces back to Swift's viral moment when she wore a custom Chi…  ( 5 min )

👉 Spec (Specification) = The answer to “How should this system work?” 🎯 To test effectively, you need to clearly understand the system before you start testing. 📚 Common Types of Specs Depending on your development process (Waterfall, Agile, Scrum…), you may encounter various types of specs. Business Requirement Document (BRD) 👉 Describes the business-level needs and goals. Explains the problem the system is solving Doesn’t go into technical details Read by: Business Analysts (BA), clients, PMs, and QA User Story (Agile) 👉 Describes features from the user’s perspective. Example: "As a user, I want to transfer money between accounts so I can manage my finances." Usually includes: Acceptance Criteria (when the feature is considered acceptable) Definition of Done (when the feature is complete) Design Spec (Figma / Wireframe / UI Flow) 👉 Describes the UI layout and navigation. API Spec (Swagger / Postman) 👉 Describes backend API details: endpoints, methods, parameters, responses, error codes. Use Case / Flow Chart / Sequence Diagram 👉 Visual representations of process or user flow. ✅ Conclusion As a tester, you're not just someone who follows checklists. You're responsible for ensuring product quality, and that starts with understanding the requirements. Want to test right? → Read the spec. Want to test thoroughly? → Analyze the spec. Want to test smart? → Think like a user, a BA, and a developer.  ( 3 min )

Sound familiar? You ask an LLM to write a function and get back brittle code with a missing await or a security hole. LLMs excel at high-level thinking—architecture, structure, and data flow. But they stumble on implementation details. Forcing them to write code is using them for the wrong job. So, let's change the approach. Instead of asking an LLM HOW to do something, let's give it a tool to describe WHAT needs to be done. Serverokey is an engine that lets your LLM fill out a simple, clear blueprint—a single manifest.js file—instead of writing code. The core idea: Your LLM is the architect, not the bricklayer. Stop prompting like this: 😫 Ineffective: "Write an Express route that connects to the DB, fetches a user, checks if they're an admin, and then renders the admin dashboard." Start …  ( 4 min )

You wrote some code. You ran it. And then your array went from a list of users to an angry collection of undefined, NaNAnd more bugs than a summer camping trip. Staring at map, filter, and reduce like they were ancient scrolls written in Elvish. Copy-pasting from Stack Overflow like a caffeinated zombie. Wondering why the heck splice just murdered half my data. But here’s the truth: mastering arrays is non-negotiable. If you’re fumbling with arrays, you’re fumbling with everything. Web apps, APIs, UIs — they all depend on your ability to tame this glorious beast. So buckle up. I’m about to drop 25 methods that will make you look at arrays like a surgeon looks at a scalpel.

So I was working on this side project, and I realized something embarrassing: my API was basically broadcasting my entire database structure to anyone who sent a malformed request. You know that moment when you're testing your endpoint and you get back something like this? { "error": "PrismaClientKnownRequestError: \nInvalid `prisma.user.create()` invocation:\n\n{\n data: {\n email: \"user@example.com\",\n ~~~~~~~~~~~~~~~~~~\n name: \"User\"\n }\n}\n\nUnique constraint failed on the fields: (`email`)" } That's not just ugly—it's a security nightmare. It is basically handing over your database blueprint to anyone who hits your endpoints. What I really wanted was something clean like this: { "status": "fail", "message": "Duplicate value found for email. Please use a …  ( 9 min )

Did you ever think about using nestjs as your SSR Server for angular v20 ? First of all we need to install a few dependencies to our angular application. Those are: "@nestjs/serve-static": "^5.0.3", "@nestjs/cli": "^11.0.7", "@nestjs/common": "^11.1.5", "@nestjs/core": "^11.1.5", "@nestjs/platform-express": "^11.1.5", "@nestjs/schematics": "^11.0.5", "@types/node": "^20.19.8", "reflect-metadata": "^0.2.2", ` After that we need to define a middleware to use the AngularNodeAppEngine within our NestJS server. After that we need to create our AppModule where we register the Middleware and import the ServerStaticModule for static content serving. This will look like this: That's basically all we need. server.ts within the Angular App will look like this: Now if you run npm run start and have SSR enabled you will see that the NestJS server starts up perfectly fine. Please note that this is just a simple POC and needs some tweaking as for example sometimes when the app is reloading the server is not shutting down completly or npm run build doesn't work at this time. But i will try to improve my POC github repo to fix this issues. You can find the minimal POC repo here: https://github.com/xsip/ng-nest-ssr Hopefully this helped you in some way.

If you’re like me, you probably use Git every day with commands like git add, git commit, and git push. But Git has superpowers—commands that can save hours, rescue broken codebases, and help you understand who wrote what and why.

A risk register is one of the most powerful tools in an SRE's arsenal for maintaining system reliability. By systematically documenting potential threats to your infrastructure and services, you can shift from reactive firefighting to proactive risk management. A risk register is a living document that catalogs potential risks to your system's reliability, their likelihood of occurrence, potential impact, and mitigation strategies. For SREs, it serves as a central repository for tracking everything from dependency failures to capacity constraints. Think of it as your team's collective memory of what could go wrong, paired with actionable plans to prevent or minimize damage when risks materialize. Every effective risk register should include these essential elements: Risk ID and Description…  ( 7 min )

In the gleaming laboratories of AI research, machines are learning to see the world as we do—almost. Deep within the tangled neural networks of today's most sophisticated vision-language models lies a peculiar deficiency: they struggle profoundly with the concept of absence. While a radiologist can confidently report "no tumour present," these AI systems falter at such seemingly simple negations. This blind spot isn't merely an academic curiosity—it represents a critical vulnerability as AI increasingly infiltrates high-stakes environments like medical diagnostics, where what's not there often matters just as much as what is. The control room at London's University College Hospital resembles something between a trader's floor and a spaceship bridge. Dozens of screens flicker with radiologi…  ( 11 min )

I’m always curious how much an AI “pair programmer” in the terminal can help an enterprise dev get stuff done. To find out, I tried five popular command-line coding agents – from ForgeCode to Google’s new Gemini CLI, running real coding tasks (writing features, debugging, refactoring, etc.). I watched closely for speed, reliability, code quality, and integration. What I found was eye-opening: these tools work, but in ways I didn’t expect. Some delivered code in a flash, others excelled at understanding a messy multi-file project, and all had their own quirks (for better or worse). Below, I break down each agent, how I set it up, what I tested, and my verdict, with installation steps and links to their GitHub repos so you can try them too.

Introduction This article serves not only as a guideline where I share my experience, but also as a personal reminder, a note to myself to stay true to how I'm supposed to do my job properly at all times as a Principal Engineer, responsible not only for producing quality software, but also for supporting other developers and more. Just to be clear, this article isn’t specifically about my role, rather it’s about the management role in general. Let’s skip the usual boring introduction about how management is one of the most important roles in business, sports, or anywhere else — that’s basic stuff, and everyone should already know it. If you’re a manager and you don’t agree, I suggest taking a moment to seriously reflect on your career. I became a Senior Software Engineer at 24 — and boy,…  ( 9 min )

Alright, let’s cut the fluffy motivational poster nonsense. You’re here because you’ve probably thought, “Should I tell my friend/cousin/that one guy who can’t set up Wi-Fi to learn programming?” And here’s my brutally honest take in 2025: No. Please. Stop. Let them be free. Let me explain why this digital insanity needs to end—with proper examples, spicy humor, and a whole lot of keyboard-induced trauma. In 2025, everyone thinks they’re a dev. Your uncle makes AI-generated memes? “I’m an AI prompt engineer.” Your cousin made a Notion dashboard with pastel colors? “I’m a software architect.” Some guy connected ChatGPT to a Google Sheet and now charges \$300/hr? “I build AI apps.” At this point, teaching someone programming is like handing out guitars at a family reunion. can learn, but sho…  ( 5 min )

In this three part tutorial, we’ll explore the core concepts of player management in Horizon Worlds, focusing on how to structure your scripts for both server and local player controllers. Our objective is to build a robust foundation that enables seamless communication and synchronisation between all players in your world. After the completion of this three part tutorial you will have an avatar that can double jump and sprint for short periods of time. Horizon Worlds uses scripts to define interactive behaviours and game logic. These scripts are written in TypeScript, a strongly-typed superset of JavaScript, which helps catch errors early and improves code maintainability. There are two main types of scripts in Horizon Worlds: Server Scripts: These run exclusively on the server and are re…  ( 8 min )

This is a submission for the World's Largest Hackathon Writing Challenge: Building with Bolt. A travel-focused social app which helps travelers connect, plan, build and share their travels. I have always been bad at frontend web app development. This is the first time I have been able to build and submit an app with a frontend all by myself. Bolt's integration with Supabase and GitHub helped a lot. It could easily make changes to the Supabase setup which took away a lot of manual work. Of course the actual coding of the app is awesome considering the size of the app and a major refactoring wherein I wanted to move CSS styles to respective components from 1 huge CSS file :) Supabase challenge - This project has used Supabase extensively for storing all data, using edge functions for creatin…  ( 4 min )

I was just reading a paper about Mercury, an AI language model that generates text and code incredibly fast by using a different method called “diffusion.” Before I explain it a bit more, if you’re interested in reading the full paper, you can check it out at: https://arxiv.org/pdf/2506.17298 How Traditional AI Models Work Traditional AI models use autoregressive processing, working sequentially like a person talking — word by word, or in AI terms, token by token. Each token depends on the previous one. This approach is accurate but slow because of its one-by-one process. It’s like someone writing a sentence word by word. How Mercury Works: Diffusion Think of it like a sculptor starting with a rough block of stone and quickly chipping away to reveal the final statue. This approach is much faster on modern computer chips (GPUs). Their big idea is: From fixing to creating How they train the AI Start with something perfect: They begin with something flawless, like a piece of code that actually runs. How to generate a new answer Give it pure chaos: Instead of providing damaged code like in the training phase, they give it completely random gibberish that matches the length of the expected answer. A Final Piece: The AI’s “Brain” So, in summary: they taught a popular type of AI brain a new trick (unscrambling) which allows it to generate entire answers at once, making it dramatically faster.

Greetings, diligent developers! We've made incredible strides in mastering CSS layouts with Flexbox and Grid. Today, on Day 35, we're taking a slightly different turn, but one that is equally crucial for dynamic and interactive styling: CSS Pseudo-classes and Pseudo-elements. These powerful CSS features allow you to style elements based on their state (like when a link is hovered over) or to style specific parts of an element without needing to add extra HTML. Think of them as CSS superpowers that let you target elements or even parts of elements that don't have unique IDs or classes, or that change based on user interaction. At first glance, pseudo-classes and pseudo-elements might sound intimidating due to their names. But in practice, they are incredibly intuitive and open up a world of…  ( 8 min )

What is Infrastructure as Code (IaC) ? Infrastructure as Code (IaC) is a declarative approach to provisioning and managing infrastructure using tools such as Terraform, CloudFormation, Ansible, and others. With IaC, there’s no need to manually log in to cloud provider consoles like AWS, Azure, or GCP to create infrastructure resources. The core idea of IaC is that you define your infrastructure in code—allowing you to create, update, and destroy resources programmatically. By using IaC across both on-premises and cloud environments, organizations can deliver dynamic, scalable infrastructure to internal teams and ensure a seamless experience for customers. IaC has become a foundational practice in DevOps and cloud-native engineering, empowering teams to build scalable, consistent, and rep…  ( 4 min )

Project Architecture This project (Github branch main) I built this app entirely in CPP and I used the CrowCpp framework to run it. I created some custom includes with all the custom libraries for each one. Mysql.h MySQL Connector/C++ to grant the ability to my application to be able to connect to my mysql database. I got the sql cpp con from this package libmysqlcppconn-dev. Player.h which comes in as a new player gets created. It handles the initialization stuff like initial xp date of creation xp required. Basically sets the player up. PlayerGrowth.h comes in when player sets or completes tasks. The calculation of rewarding xp by fetching from database and setting new ones back. Setup.h is the bootstrap for the application that creates the tables required for the application in the database. I used CMAKE as my compiling tool followed by make. So in summery as new player is created Player.h comes in to do the formalities with giving back the UID generated to the player. As in LoadGame section when tasks created or completed and displaying of stats is handled by PlayerGrowth.h and as the app starts the Setup.h bootstraps it. Mysql.h works behind for the communication from app to database. The Auxiliary.h is just another custom header I made to enforce DRY(Don't Repeat Yourself)  ( 4 min )

You’ve seen the headlines: “AI will write all code by 2030!” “Coding is dead!” “Learn prompt engineering instead!” But here’s what nobody’s saying: AI is a mirror. It reflects what you feed it. If you don’t understand the basics of coding, you’ll stare at that mirror like a lost tourist—no map, no direction, just confusion. This isn’t a doomsday scenario. It’s an upgrade. And I’ll show you why mastering coding fundamentals + AI is the cheat code to dominating the future. Part 1: Why Basics Are Your Unshakeable Foundation (Build credibility with logic and relatable analogies) 1.1 The…  ( 5 min )

Remember when autocomplete felt like magic? Now entire codebases are being written, tested, and debugged — by AI agents. We’ve entered a new era of software development. AI-powered coding agents are no longer just copilots suggesting a line of code — they’re task-oriented, goal-driven tools that help developers automate entire workflows: writing boilerplate, handling documentation, fixing bugs, managing PRs, and even scaffolding new features from a simple prompt. What’s wild? Many of these agents are open source, CLI-native, and incredibly fast. Instead of spending hours piecing together files and functions, developers are now outsourcing grunt work to agents that live in their IDEs, repos, or terminals. Whether you're a solo indie hacker, part of a lean startup team, or contributing to la…  ( 8 min )

Sustainability is no longer a side initiative—it’s becoming the heart of how forward-thinking companies operate. At Amazon Web Services (AWS), one leader is helping shape a future that serves people, profits, and the planet. Meet Hilary Tam, AWS's Commercial Sustainability Leader for Europe, Middle East, and Africa (EMEA), who is turning bold climate ambition into practical, scalable solutions. Hilary’s passion for sustainability began early, but a visit to a multi-generational green tea farm in China left a lasting impression. She witnessed firsthand how unpredictable climate patterns were impacting crop quality and livelihoods. That experience sparked a mission: to use human-centered innovation to tackle complex environmental issues. At AWS, Hilary collaborates with customers and partner…  ( 4 min )

We’re entering an era where raw computing power is no longer the main force driving AI forward. What matters more now is contextual intelligence, in other words, the ability for machines to understand, remember, and reason about the situations they operate in. For example, Olivetti’s Active Badge system tracked office movement, but couldn’t adapt to human nuance. There was no flexibility or personalization. Just rigid rule trees. These systems were functional, but not intelligent. Phase 2: Learning Context (2000s–2010s) With the rise of machine learning, systems began to learn from data instead of hardcoded rules. Probabilistic models introduced uncertainty tolerance. Context became a statistical pattern, not just a variable. Think of early email spam filters. They began to "learn” user be…  ( 4 min )

Have you ever tried callforwards? If you've used Express.js before, it's the same concept, but for the front-end: you have a pipeline of middleware functions and you put all your logic inside. In Express, the library takes HTTP requests, runs your middleware and generates HTTP responses. On the frontend, you have Rimmel.js which takes not HTTP requests but DOM events, then processes your middleware and displays the results. If you like how simple and straightforward is Express on the back-end, you'll probably appreciate the same fluency on the front-end, too. Let's compare the two libraries and see how we can leverage similarities in their architecture to get started quickly. In Express you can write a handler function for an API that returns a number that's twice the number provided in in…  ( 4 min )

When the concept of MCP (Model Context Protocol) first emerged, I felt a jolt of genuine excitement. This was it. This was the key that would let us unlock the true potential of LLMs, allowing them to interact with tools and the real world. I jumped in headfirst, my mind buzzing with ideas for truly intelligent agents. My initial excitement quickly turned into a grinding frustration. The cycle became depressingly familiar: Spend hours figuring out the right API calls for a tool. Manually edit a sprawling, unforgiving config.yaml file. Worry constantly about accidentally committing secret keys. Finally get it to work, only to have the agent forget a crucial piece of information from the previous turn. I spent more time debugging YAML syntax and juggling API keys than I did thinking about th…  ( 4 min )

When I moved from traditional on-prem MDM to the cloud version of Informatica MDM on IDMC, one of the first surprises came during something I thought I already understood: match & merge logic. I had already spent years working with match rules, comparators, survivorship, trust — so I assumed this would be a straightforward migration. I was wrong. What I quickly realized was that even though the concepts were the same, the way the Cloud MDM engine handles match/merge is different enough that we had to rethink a lot of things from scratch. Here’s what I learned, and what you should be aware of if you're making the shift. **🧠 Rule Design Has Moved to UI, But Complexity Remains You design match rules directly in a no-code visual interface You configure comparators and thresholds using dropdow…  ( 4 min )

Mastering PDF Compression: Optimal Strategies for Developers PDF compression is a critical skill for developers working with documents, as it directly impacts storage, bandwidth, and user experience. Today, we'll dive into advanced algorithms, implementation techniques, and performance optimization strategies to help you master PDF compression. At the heart of PDF compression are several algorithms that work together to reduce file size. The most common ones include: Run-Length Encoding (RLE): A simple form of data compression where sequences of the same data value (runs) are stored as a single data value and count. LZW (Lempel-Ziv-Welch): A lossless data compression technique that replaces repeated occurrences of data with references to a single copy. Flate (Zlib/DEFLATE): A lossless co…  ( 4 min )

In the ever-evolving world of web development, writing clean and meaningful code is more important than ever. One of the most essential practices for building modern, accessible, and SEO-friendly websites is the use of Semantic HTML. Unlike generic tags that only define how elements should look, semantic HTML elements describe the purpose and structure of content. This not only improves the user experience, especially for those using assistive technologies, but also helps search engines understand and rank your website more effectively. In this article, we’ll explore what semantic HTML is, why it matters, and how it benefits both SEO and accessibility. A Brief History of Semantic HTML . As web standards evolved, especially with the rise of CSS in the late 1990s, developers were encouraged to separate design from meaning. What is Semantic HTML? or , semantic tags like , , , , and give meaning to the content. 🧠 In Simple Words: My Blog This clearly tells that “My Blog” is the header of the page.

Architecture diagrams are everywhere. But let’s be honest… they rarely tell the full story. If you've ever had to "present your architecture" and ended up talking for 20 minutes to explain your diagram — you're not alone. In this video, we unpack why even the best diagrams (C4, UML, arc42...) often fail to communicate what stakeholders really care about: ✅ What's the business context? We explore what executives and business leaders are actually asking: To bridge that gap, I introduce The Architecture Work Canvas — a simple one-page tool that brings together context, stakeholders, and outcomes in a clear, actionable way. It’s part of a broader initiative I call QTAM: The Quick Technical Architecture Method — built for developers, tech leads, and architects who want to turn technical insight into business impact. 📌 Learn how the Canvas complements C4, arc42, and TOGAF-based approaches 🚀 Ready to move from misunderstood diagrams to meaningful conversations? https://qtam.morin.io 🎓 Also available as a full online training on Udemy — theory + real-world practice + downloadable tools: https://qtam.morin.io 💬 What’s your take on architecture diagrams?

Q1 :- Reverse Right-Angled Triangle Made of Asterisks Write a JavaScript function that prints the following reverse right-angled triangle pattern of asterisks, for a given positive integer n: Input = n The outer loop is responsible for printing the rows. It starts from n and continues as long as the value is greater than 0. In each iteration, it runs the inner loop and then decreases the value of i by 1. The inner loop is responsible for printing the columns (like *, numbers, etc.). It starts from 0 and continues until it is less than the current value of i (from the outer loop). Since the outer loop decreases i in each step, the inner loop also runs fewer times in each new row. **** *** ** * function printReverseTriangle(n) { let output = ""; // Outer loop: from n down to 1 …  ( 4 min )

I encountered a strange scenario while adding a feature to the Admin Dashboard. The problem was that I had a mutator method in my model for hashing the password: use Illuminate\Support\Facades\Hash; /** * Set the model password attribute. */ public function setPasswordAttribute($value): void { if (!empty($value)) { $this->attributes['password'] = Hash::make($value); } } Later, while logging into the admin dashboard using a simple password (since it was on the local stage), I discovered something odd: the password was being updated after I logged in. This happened because the input password was passed through the mutator again, causing it to be re-hashed. To test further, I manually hashed a strong password using Tinker and attempted to log in again. Surprisingly, this t…  ( 3 min )

A growing chorus of developers claim that Stack Overflow has lost its value. The complaints are familiar. Too many outdated answers. Too many duplicates. Unfriendly moderation. But beneath these grievances lies a deeper, often ignored issue. The problem is not the site itself. The problem is how developers get there. Most devs use Google to reach Stack Overflow. But Google’s search results have changed. They are noisier, more commercialized, and increasingly shaped by ad revenue, behavioral tracking, and AI curation. As a result, answers that used to sit at the top of a search now get buried under auto-generated blurbs, sponsored links, and irrelevant summaries.

Social media and various other online platforms require some sort of identity to provide their services and to customize experience to us. What does it mean exactly and how does it work in practice? Currently most, if not all, of these platforms - Twitter/X, YouTube, Reddit, LinkedIn, Facebook, Instagram, GitHub, Amazon, Spotify and the like - are account-based. We sign up to create an account that is then stored on the service servers and controlled by it. Each time we want to use the service, we sign in with the previously configured credentials and if everything is correct - we are granted access to the service. To control claimed identity, we must prove to the service owner that we are who we say we are. This is the prevailing identity model that is used by most digital services and networks - Centralized. But, there are other possibilities as well: Federated Decentralized Delegated each of them coming with a different set of Incentives and Tradeoffs. We are about to examine all of them, pondering the following questions: Why do we rarely see and use anything different than the centralized model? What problems do they solve? What problems do they cause? What use cases do they fit the most? Is any of them always better, or it depends (on what)? And finally - does the currently dominant identity model must be fixed, or it serves us well and nothing needs to be done?

Background In the Action Figure category on eBay, the listing UI only provides two condition options: NEW and USED. However, when creating a SKU using the eBay Inventory API, specifying "USED" directly causes an error. According to eBay's API specification, the enum value "USED" does not exist. UI Label → "USED" API Expected Value → "USED_EXCELLENT" (Condition ID: 3000) So, to reproduce the UI’s “USED” condition in the API, you need to use "USED_EXCELLENT" instead. createOrReplaceInventoryItem - Inventory API ConditionEnum Definitions "USED" \ curl -X PUT 'https://api.ebay.com/sell/inventory/v1/inventory_item/test-sku-001' \ -H "Authorization: Bearer DUMMY_ACCESS_TOKEN" \ -H "Content-Type: application/json" \ -d '{ "condition": "USED", "product": { "title": "Dummy…  ( 3 min )

No one actually cares about my programming environment journey, but I’ve often been asked to share it, perhaps for the sake of social media algorithms. I post it here, so later, I can copy and paste this conveniently. My first computer, in the sense that I, not someone else, made the decision to buy it, ran Debian in 2002. It was a used Compaq desktop with a Pentium II processor, which I bought from Zeer Rangsit, a used computer market that may be the most famous in Thailand these days. When I got it home, I installed Debian right away. Before I bought my computer, I had used MBasic, mainly MS-DOS, Windows 3.1 (though rarely), and Solaris (remotely). For experimentation, I used Xenix, AIX, and one on DEC PDP-11 that I forgot. Since I started with MBasic, that was my first programming environment. I learned Logo at a summer camp, so that became my second. Later, my father bought me a copy of Turbo Basic, and at school, I switched to Turbo Pascal. After moving to GNU/Linux, I used more editors instead IDEs. From 1995 to 2010, my editors were pico, nvi, vim, TextMate, and Emacs paired with GCC (mostly C, not C++), PHP, Perl, Ruby, Python, JavaScript, and SQL. I also used VisualAge to learn Java in the 90s. I tried Haskell, OCaml, Objective C, Lua, Julia, and Scala too, but it was strictly for learning only. After 2010, I used IntelliJ IDEA and Eclipse for Java and Kotlin. For Rust (instead of C), I used Emacs and Visual Studio Code. I explored Racket for learning purposes, then later started coding seriously in Clojure and Common Lisp. I tried using Vim 9.x and Neovim too, they were great, but not quite my cup of tea. In 2025, a few days ago, I learned Smalltalk with Pharo to deepen my understanding of OOP and exploratory programming.  ( 3 min )

This was originally a late-night rant I posted in the Facebook group. Since it got a nice response and I’ve been meaning to try my hand at dev.to, I’m recycling it as my very first story here. Software Engineers, are you ready for the next‑gen challenge? Hold on, I’m not talking about vibe‑coding or AI agents! Sure, those are cool. In my years in the industry I’ve hopped across all sorts of companies — multinationals, mid‑sized firms, even tiny firms. And more often than not they didn’t hire me to play with the latest cutting‑edge toys. I know those shiny tools, sure — but there’s always a queue of rock‑star devs fighting to mess with them.

Ever been on a site where everything just feels right? The button hovers softly, a small label appears just when you need it, and scrolling flows section by section like turning a page. It’s not magic. It’s just good use of CSS. And with a little help from AI, you can make it happen without digging through endless documentation. In this post, we’re focusing on three small details that go a long way: Transitions that add smoothness Tooltips that offer just-in-time info Scroll snapping that makes navigation feel intentional They’re not flashy but they make your site feel polished and pleasant to use. Without transitions, everything on your site happens instantly, which may feel a little jarring. Transitions slow things down just enough to feel natural. Hover over a button, and it fad…  ( 5 min )

Posted originally to binarypatrick.dev When using docker compose, I recently got into adding health checks for my containers. This helps a lot with startup, especially with dependednt containers, but I was under the impression if I had something like restart: always or restart: unless-stopped, it would automatically try and restart my container. That's just not the case so I looked for something that might. There is a container you can user to monitor the other running containers and restart them if they are unhealthy. It's called autoheal by a dev named Will Farrell (no relation?). The only issue is that running a container to make sure my other containers are running seems a little like asking the kids to watch each other, and also, and maybe more importantly, I don't know Will, and his …  ( 4 min )

We've all experienced that frustrating moment when an AI starts answering your question, then suddenly says "I can't assist with that." It tricks your brain You start mentally following the solution, then have to abruptly stop that thought process. It wastes time Reading half an answer takes longer than getting an immediate "I don't know". It feels dishonest Like when someone pretends to help but is actually avoiding the work. Common situations: Starts explaining a technical concept in detail... then refuses to finish Begins walking through a solution step-by-step... then quits at the most critical point Lists multiple setup steps... but won't provide the actual resolution Early warnings when confidence is low Clear boundaries about what can/can't be answered Partial solutions with explanations of limitations What's the most important improvement AI systems could make to handle these situations better?  ( 3 min )

Even if I never reach the ideal destination, at least I will have these treasured memories. On July 18, 2025, after nearly a month-long performance optimization campaign, I ran a standard Lighthouse audit. The result — 100 on mobile, 100 on desktop. Against all odds, we achieved a perfect score. No marketing. No compromises. No team. No budget. Just me — and Wan’er (my AI).

Sentium Pico - Synthetic Life Simulation An experiment in artificial consciousness within PICO-8's constraints I've been fascinated by consciousness research for years, and wanted to see what happens when you try to implement some of those theories in the most constrained environment possible - PICO-8's 128x128 pixels and tiny memory space. Sentium Pico started as a simple question: can you create something that feels "alive" using just colored pixels?

Promises em Node.js: Paralelo, Sequencial e Corrida – Como Escolher? Em JavaScript (e especialmente no Node.js), Promises são uma das ferramentas mais poderosas para trabalhar com código assíncrono — aquele que não bloqueia o fluxo principal enquanto espera por uma resposta, como uma chamada de API ou leitura de arquivo. Mas… quando você tem várias Promises ao mesmo tempo, como decidir a melhor forma de executá-las? Neste artigo, vamos explorar os três padrões mais importantes para isso: Execução Paralela Execução Sequencial Corrida (Race Condition) E sim, vou te mostrar com exemplos práticos e simples como isso funciona.

I’m working on programming a chatbot. Here’s what my MVP looks like and how I plan to start: The chatbot will initially integrate with WhatsApp. (Later on, I want to make it omnichannel to support other social networks.) It will be a multi-client chatbot. I’ll build the backend in Python, and each customer will integrate it with their own WhatsApp account. Each customer will have a Google Sheet on their computer containing their data. At the beginning, the chatbot will read and retrieve information from that sheet. (Later, I plan to develop a simple ERP system and a dashboard so customers can manage the chatbot more easily.) I’m based in Peru, South America. I want to start with low-cost tools, databases, and infrastructure. However, as the project grows, I plan to invest in better technology, infrastructure, and a team. Eventually, I want to integrate the chatbot with an ERP. It will start with just a few basic modules, but I’ll gradually add more features as the platform grows. I’d appreciate any suggestions, opinions, or best practices on how to build a scalable solution from the beginning—so I don’t face limitations or obstacles later on in terms of chosen technologies, databases, backend language, or WhatsApp API providers (like Twilio or 360Dialog). Should I use a provider at first, or would it be better to build the WhatsApp integration myself without intermediaries?  ( 3 min )

Remote hiring has revolutionized global access to talent—but it’s also opened the door to sophisticated fraud. Here’s how one interview shattered our assumptions and changed our approach. The Interview That Raised Alarms We were hiring a developer through LinkedIn—standard process in 2025. Applications poured in, especially from Eastern Europe. On paper: impressive résumés, solid GitHub profiles, fluent English. Everything looked right. But during interviews, the reality didn’t match the claims. Candidates who identified as Eastern European showed clear signs of being from entirely different regions—mostly Asian descent, struggling with English, and no grasp of local geography or culture. Diversity isn’t the issue here; deception is. Deepfake in a Dev Interview? One candidate claimed to live in a city I knew well. Casual questions about the area revealed zero local knowledge. Then came the real shock: the candidate was using real-time face-swapping software to appear Eastern European on camera. The effect was subtle but noticeable—slight glitches, uncanny expressions, and delayed eye tracking. We weren’t just dealing with résumé inflation. This was full-blown identity fabrication. The Tech Behind the Scam These weren’t isolated cases. Here’s what we’re now seeing: The tools are public, cheap, and scarily effective. Why This Matters The risks are serious: How We Adapted Our Process To combat this, we’ve overhauled our hiring pipeline: ✅ Enhanced Verification 🛡️ Technical Defenses 🌍 Cultural & Linguistic Checks The Human Cost The tragedy is that honest candidates—especially from fraud-prone regions—now face unjust suspicion. The actions of a few are making it harder for the many. Moving Forward Remote work is here to stay. But so is deception. Our choices now will define whether we remain open to global talent or retreat behind geographic firewalls. Let’s do better: ⸻ Have you seen similar fraud in your hiring process? How are you adapting? Let’s compare notes below.  ( 4 min )

Authentication Flow: Two-Token Strategy Github Code Link In this application, we employ a two-token strategy for authentication to enhance security and user experience. This involves an Access Token and a Refresh Token. A short-lived JSON Web Token (JWT) that the client sends with every request to access protected resources. Its short lifespan (defined by JWT_ACCESS_EXPIRES in env.ts) minimizes the risk if it's ever compromised. A long-lived JWT used solely to obtain a new access token when the old one expires. It is stored securely in an httpOnly cookie, making it inaccessible to client-side JavaScript. Its longer lifespan is defined by JWT_REFRESH_EXPIRES.

To use the SkyFi Platform API, you need to have a SkyFi Pro account and obtain an API key: Sign up / Upgrade to SkyFi Pro: Create a SkyFi account (or log in to your existing account) at app.skyfi.com and upgrade to a Pro plan. Only Pro accounts have access to API keys. Find your API key: Once you have a Pro account, navigate to the My Profile section on the SkyFi app/website. There you will find an API key that you can copy. Authentication: All API requests must include this API key in the header. Use the header X-Skyfi-Api-Key: for authentication. Without a valid API key, requests will be rejected with an authentication error (HTTP 401). Start with open data (free) orders: A recommended first step is to test the API using open data imagery (such as Sentinel-2) which is free of charge. This lets you verify that your requests and delivery setup work correctly without incurring costs. To do this, you can perform an archive search with the openData: true filter (to find free imagery) and then place an order for one of those results (open data orders cost $0). Review documentation and examples: The SkyFi API has interactive documentation (Swagger/ReDoc) and example code in multiple languages. You can reference these to understand how to format requests. For instance, the documentation shows how to form requests in Python, JavaScript, etc. Once you have your API key and are comfortable with the API endpoints, you can start integrating SkyFi services into your application.  ( 3 min )

At Kaizen Agent, we’re building something meta: an AI agent that automatically tests and improves other AI agents. Today I want to share the architecture behind Kaizen Agent, and open it up for feedback from the community. If you're building LLM apps, agents, or dev tools—your input would mean a lot. One of the biggest challenges in developing AI agents and LLM applications is non-determinism. Even when an agent “works,” it might: Fail silently with different inputs Succeed one run but fail the next Produce inconsistent behavior depending on state, memory, or context This makes testing, debugging, and improving agents very time-consuming — especially when you need to test changes again and again. So we built Kaizen Agent to automate this loop: generate tests, run them, analyze the results,…  ( 5 min )

When in doubt, remember that Rust prioritizes preventing unexpected changes to data. Ownership in Rust is a unique concept every Rust developer should be acquainted with. Ownership is a way Rust manages its memory. It lies at the heart of how Rust handles memory safely and efficiently, without needing a garbage collector. Each value has a single owner. fn main() { let country_a = String::from("Ireland"); // country_a goes out of scope here } From the above example, countryA is assigned a value of string — Ireland. Which automatically means countryA is the owner of the value. When countryA moves to the second line, it goes out of scope, and Rust automatically cleans up the memory. A value can only be owned by one variable at a time. fn main() { let country_a = String::from("Ireland")…  ( 6 min )

If you're a new Scrum Master — or managing your own agile process with Zenhub — chances are you’ve thought: “Wait… am I using this the right way?” I’ve been a Scrum Master for over 4 years, and I’ve run 100+ Sprints across multiple teams. Zenhub is powerful, but without a clear setup and a lightweight process, it can get messy really fast. This post is a breakdown of how to use Zenhub effectively as a Scrum Master, with just the essentials: Let’s jump in. Your Zenhub Board is your team’s visual heartbeat.

DHH told me I'm an idiot if I don't use Ruby. No, he didn't actually say that, but I just listened to this 6 hour long Lex Fridman interview with DHH. DHH's enthusiasm inspired me to finally give Ruby a try. So here I am a couple days into learning Ruby, and it has been a lot of fun! First things first, Perl used to be my main scripting language. I know. I know. It's a weird one, but you can do so many cool things when a language has first class regex support. I've tried to like Python, but I do not like the syntax and writing in it feels abrasive. I do not like the space/tab formatting of Python, and I often butt up against one of Python's core tenets: "There should be one-- and preferably only one --obvious way to do it." Eh. No! Give me options! More options may make the language more difficult to learn, but having shortcuts makes the programmer experience more enjoyable as you gain language mastery. I like languages that give me the tools to shoot myself in the foot, and I don't mind a steep learning curve (I use Neovim btw) if the payoff is satisfying. I love the flexibility of Perl, but I'm looking for something to replace Perl's acid trip syntax. Ruby is supposedly pleasant, so here we go. puts "hello world!" puts "To be continued ..."  ( 3 min )

It's 2025. Everyone has a ChatGPT tab open and says the same thing: “I’m going to generate passive income using AI.” These people usually: Panic when they open Excel, Get stressed downloading a font on Canva, But fully believe that “if I get ChatGPT to write me an e-book, the dollars will rain down.” This post is a lighthearted portrait of the new generation of “entrepreneurs” who see AI as a magic wand. The plan is simple: Ask ChatGPT to write a book. Use Midjourney to create the cover. Convert it to PDF for free.

When working with SQL CASE statements for data bucketing, the order of conditions can make or break your queries. Let me show you why this matters and how to write more robust SQL. Let's start with a simple dataset to demonstrate the concept: import pandas as pd import numpy as np from duckdb import sql # Create sample data N = 10 np.random.seed(42) # For reproducibility df = pd.DataFrame({ 'id': list(range(N)), 'value': np.random.uniform(0, 1, N), }) This creates a DataFrame with random float values between 0 and 1 that we want to bucket into categories. The most common way to write a CASE statement is: SELECT *, CASE WHEN value < 0.2 THEN 'low' WHEN value < 0.5 THEN 'medium' ELSE 'high' END AS value_category FROM df This works perfectly fine an…  ( 4 min )

ResNeXt introduces a simple and highly effective architectural innovation to convolutional neural networks: cardinality, the number of parallel paths or groups within a convolutional layer. Unlike traditional methods that focus solely on depth or width, ResNeXt leverages grouped convolutions to split computations across multiple branches, reducing parameter count while maintaining and often improving performance. Grouped convolutions are a variation of standard convolutions where the input and output channels are split into separate groups, and convolutions are applied independently within each group. Normal Convolution (groups = 1): processes all input channels Grouped Convolution (groups > 1): divides input channels into n groups Cardinality refers to the number of parallel paths or gro…  ( 4 min )

Working with database concurrency can be tricky, especially when dealing with multi-user environments. Today, I'll walk you through Uniface's lock statement, a powerful tool for managing database occurrence locking. This article was created with the assistance of AI and is based on the Uniface Documentation 10.4. The lock statement in Uniface locks the database occurrence of the current occurrence, ensuring that only the current process can modify it. This is crucial for maintaining data integrity in concurrent environments. Understanding the return values is essential for proper error handling. Here's what you need to know: Status Value Meaning 0 ✅ Success - Occurrence is locked and can only be modified by the current process -1 ❌ No active occurrence or no entities painted on th…  ( 4 min )

As a developer working with Uniface 10.4, you'll often find yourself managing files and archives programmatically. Today, I want to share insights about a powerful yet often overlooked command: lflush. This post is based on the official Uniface documentation 10.4, and I had some assistance from AI to structure this content effectively. The lflush command is a ProcScript statement that completes file management transactions for open zip archives or XML files, then closes them. Think of it as the "save and close" operation that ensures your file operations are properly finalized. Uniface keeps files open during operations to avoid performance issues from repeatedly opening and closing files. While this optimization is great for performance, it means you need to explicitly close these files w…  ( 4 min )

The Idea I don't know about you, but I frequently use messaging apps for note-taking. I like typing in a thought, an idea, a measurement, and immediately having the timestamp appended. I thought I should build a note-taking app based on this idea. The user interface should be that of a messaging app, but it's all in service of taking quick notes. Servers become notebooks, and channels become pages. I've already worked with React Native and Expo, so I decided to use these for the app. I have yet to decide how to persist data. The app should work offline, but I don't want to exclude the possibility of syncing to the cloud in the future. My goal is to eventually publish this on the app store.

As a Uniface developer, you might encounter situations where you need to rename directories programmatically while bypassing file redirections. This is where the ldirrename statement comes in handy! 🚀 Note: This article is based on the Uniface documentation 10.4, and I had assistance from AI in creating this content. The ldirrename statement is a powerful Uniface function that renames directories while ignoring any file redirections defined in the assignment file. Think of it as a "direct" rename operation that bypasses the usual redirection logic. The syntax is straightforward: ldirrename DirPath, NewDirName Example: ldirrename "data/exports", "saved" Parameter Data Type Description DirPath String Directory name with optional path. Can be in a zip archive! 📦 NewDirName String New directory name (no path, no trailing separator). Can also be in zip archives! The function returns values via $procerror: 0 - Success! ✅ -13 (UIOSERR_OS_COMMAND) - OS command error ❌ Pro tip: Set /pri=64 to display detailed error messages in the message frame when troubleshooting! 🔍 Ignores redirections: Unlike dirrename, this bypasses assignment file redirections Zip archive support: Works with directories inside zip files Universal compatibility: Allowed in all component types Flexible paths: Supports both relative and absolute paths Use ldirrename when you: Need to rename directories without triggering file redirections Work with zip archives containing directories Want direct control over directory operations Need consistent behavior across different deployment environments For comparison, check out the standard dirrename function if you need redirection-aware directory renaming.

Do you fixup your git commits? Fixup is a tool to change any git commit, without much trouble. So, I have three commits in my branch with the following messages: Commit A Commit B Commit C After a code review, I want to apply some changes to commit A, which is the earliest (so a simple git amend won't suffice): $ git add . $ git commit --fixup So, now I have 4 commits: Commit A Commit B Commit C fixup! Commit A I can now do an interactive rebase to "fixup" commit A: $ git rebase --autosquash -i HEAD~4 The editor opens, but the last commit is automatically moved to after commit A, and the verb is correctly set to "fixup" (which is the same as squash, only that the commit message is not preserved): pick 292ad0da8d Commit A fixup 7716e4fbce fixup!

Most developers have spent years building with frameworks like React, Vue, or Angular. But in 2025, something surprising is happening — Vanilla JavaScript is trending again. It’s not just a nostalgia trip. It's about performance, control, and simplicity. Over the years, we’ve leaned heavily on frameworks. They make things easier, but they also bloat our bundles and sometimes abstract away too much. Vanilla JS—meaning pure JavaScript without dependencies—is making a comeback because it delivers: Zero overhead Better performance on low-spec devices Full control over rendering and events In a time where Core Web Vitals matter more than ever, every KB counts. At DevTechInsights.com, we examined several landing pages. By dropping React and switching to Vanilla JS: Our TTFB dropped by 300ms …  ( 4 min )

Introduction How many habits do you currently want to build—or bad habits you'd like to break? Personally, I’m always highly sensitive to these two themes. I often find myself timing new attempts to form or break habits, reading related books, and studying the topic in depth. Why? Because I believe that what shapes a person is the accumulation of countless hours and repeated behaviors. The actions we perform unconsciously have a huge impact on the course of our lives. But in reality, it often looks like this: You get all fired up to start studying, exercising, or meditating—only to fizzle out after a few days. Meanwhile, excessive drinking or late-night social media scrolling becomes hard to quit. We’ve all been there. What plays a key role here is the brain’s novelty mechanism. Our brai…  ( 7 min )

Security breaches are becoming more expensive and harder to detect. While phishing and ransomware dominate headlines, attackers are increasingly targeting the overlooked layer of your environment: non-human identities (NHIs). Non-human identities outnumber human identities 45 to 1 in cloud systems. These include API keys, service accounts, bots, containers, and automation tools. Unlike human users, NHIs don’t log in with passwords or set off alerts. This makes them ideal targets for attackers seeking long-term access to your systems. Non-human identities are any system, service, or process that interacts with your infrastructure without being a human user. Think of APIs, scripts, CI/CD tools, containers, or cloud services. NHIs are everywhere—and their numbers grow as your environment scal…  ( 5 min )

GitHub Homepage During my junior year studies, high concurrency processing has always been one of the technical fields I'm most interested in. While traditional multi-threading models can handle concurrent requests, they often encounter performance bottlenecks when facing large numbers of connections. Recently, I deeply studied a Rust-based web framework whose high concurrency processing capabilities gave me a completely new understanding of asynchronous programming. In my previous projects, I used thread pool-based concurrency processing models. This model allocates a thread for each request, and while implementation is simple, it has obvious scalability issues. // Traditional Java thread pool model @RestController public class TraditionalController { private final ExecutorService th…  ( 8 min )

Before AI, learning to code meant starting with the basics, following tutorials, and gradually building projects. Now? It’s flipped. I often start by asking an AI to write the code. Then, when it breaks (or doesn’t work exactly how I want), I go step by step, debugging and understanding the logic. It feels like reverse learning—build first, understand later. And honestly, it works surprisingly well for rapid problem-solving. AI hasn’t just changed what we learn, but how we learn. Does anyone else learn this way? Or do you prefer the old-school approach of mastering concepts first?  ( 3 min )

In engineering culture, deadlines get a bad rap. They’re often painted as anti-agile, top-down relics of project management—tools used to crush autonomy, cut corners, or burn people out. But the truth is more nuanced: Deadlines aren’t evil. They’re data. And if we treat them that way, they can make our teams better. A deadline is a constraint. Constraints force decisions. And good engineering is full of decisions: what’s essential, what’s nice-to-have, what’s unclear, what can wait. Without a deadline, scope tends to grow. Ambiguity festers. Risk hides in corners. A well-framed deadline flushes that all out. Deadlines also help you learn: Is our estimation accurate? Is the team aligned on what “done” means? Are we prioritizing outcomes or outputs? The goal isn’t to hit the date at all costs. It’s to use the deadline to generate insight. Bad deadlines are arbitrary, inflexible, and weaponized. They don’t serve the team—they serve optics. But healthy deadlines? They energize. They sharpen focus. They unlock creativity within limits. One engineering leader I know frames deadlines like this to their team: “This is the date we’re aiming for. If we’re off, the miss is data. It means we have something to learn—about our process, our assumptions, or the way we’re collaborating.” That reframing builds trust. It gives the team ownership and accountability—without fear. There’s a reason hackathons ship wild ideas in a weekend, or why MVPs thrive on tight timelines. A deadline, held lightly but seriously, forces decisions that otherwise get deferred. As leaders, our job isn’t to eliminate all pressure—it’s to make sure pressure creates learning, not trauma. ⸻ If you’ve been burned by deadlines in the past, that’s real. But don’t throw them out. Use deadlines to illuminate, not to intimidate. ⸻ Want more insights like this? I wrote a deeper dive here: Deadlines Aren’t Evil — They’re Information  ( 3 min )

When I first started learning how to code, I knew very little about the tech industry. All I knew was that “FAANG” — Facebook, Amazon, Apple, Netflix, and Google — was where the best engineers ended up. They were the dream. The goal. The finish line. I saw the job titles, the salaries, the stories of engineers who made it there at 19 or 20. “If I don’t get into FAANG, am I even good enough?” I never said these questions out loud. But they were always there, quietly eating away at my confidence. Let’s be honest: FAANG has become more than just a collection of companies. In our industry, it’s almost a status symbol. And because of that, we rarely question it. We just chase it. We spend months grinding Leetcode, memorizing system design patterns, and reading interview guides. “Do I even want …  ( 5 min )

Sometimes I encounter this weird idea that developers don't need accessibility at all. Some people seem to believe that our development tools and resources don't need to be accessible, because accessibility is just something to do with the end users of our services. If you're one of those people, you know, disabled software developers exist. You're reading text from one right now, and I know many developers with disabilities. Yes, even blind developers. I've been writing a blog since 2019, and as an accessibility specialist, I've tried to make my blog posts as accessible as possible. In this blog post, I decided to share some of the things I've learned over the years. So, without further ado, let's get started. If you're writing a technical blog post and sharing some code, always write i…  ( 9 min )

GitHub Homepage: https://github.com/eastspire/hyperlane My journey into HTTP response optimization began during a project where we needed to serve large datasets to web clients efficiently. Traditional approaches of building complete responses in memory before sending created both latency and memory pressure issues. This challenge led me to explore streaming response techniques that could dramatically improve both performance and user experience. The breakthrough came when I realized that most web frameworks treat response generation as a monolithic operation, missing opportunities for optimization through streaming, compression, and intelligent buffering. My research revealed a framework that implements sophisticated response handling patterns optimized for both throughput and latency. HT…  ( 9 min )

GitHub Homepage: https://github.com/eastspire/hyperlane My journey into robust error handling began during a production incident where a single unhandled exception brought down our entire web service. The cascade failure taught me that error handling isn't just about preventing crashes—it's about building resilient systems that gracefully degrade under stress while maintaining service availability. This experience led me to explore error handling strategies that could maintain both performance and reliability. The critical insight came when I realized that traditional error handling approaches often create performance bottlenecks through excessive exception throwing, complex stack unwinding, and resource cleanup overhead. My research revealed a framework that implements error handling patt…  ( 10 min )

In 2017, the world witnessed one of the most devastating cyberattacks in recent history: the NotPetya attack. Unlike most malware, NotPetya wasn’t designed for profit, but for destruction. Its primary goal was to cause as much damage as possible, with Ukraine at the epicenter of this digital disaster. NotPetya is a wiper-type malware, meaning its main intent is to erase and render data unusable, rather than simply holding it for ransom like traditional ransomware. The attack quickly spread throughout Ukraine and beyond, impacting global companies like Maersk, Merck, and several others. The entry point for the attack was MeDoc, a popular accounting software in Ukraine. The Ukrainian government required companies paying taxes in the country to use MeDoc in their systems. This meant that virt…  ( 4 min )

Most founders can build amazing products. But they can't write compelling copy. Your features sound boring and technical. Customers scroll past without reading anything. Start with what it does first. Then explain what that means exactly. Finally, show the end result. This creates a clear path. Example: "Auto-backup saves work every minute. You'll never lose progress again. Sleep better knowing data's safe." Features become benefits when connected properly. Use this formula everywhere possible. Lead with customer pain first. Show how you fix it completely. End with their total transformation. Example: "Tired of manual invoicing? Auto-invoice creates bills instantly. Get paid faster, work less." Pain-first writing hooks readers immediately. They feel understood and valued. Paint their current frustrating state clearly. Show the improved reality after. Explain why it matters most. Example: "Before: Hunting through folders daily. After: Find anything in clicks. Save three hours weekly." Contrast makes benefits crystal clear. People love dramatic transformations. These formulas work for any feature. Practice them on your worst copy. Your conversion rates will thank you. Stop listing features like grocery items. Use these formulas to sell instead. Your customers will actually read everything. Sales will follow naturally.  ( 3 min )

In Google Cloud, every Virtual Machine (VM) must be connected to a Virtual Private Cloud (VPC) network. If there’s no VPC, you can’t launch a VM. VPC - A global, isolated virtual network within your GCP project. It spans all regions. Subnets are regional; each region must have its own subnet to launch resources like VMs VMs are always launched inside a subnet, which belongs to a VPC. Even though subnets are regional, a VPC itself is global. That means VMs in different regions (but within the same VPC) can communicate with each other internally, without needing external IP addresses or a VPN. Firewall rules in GCP apply at the network level, not the individual VM. Default behaviour: all incoming traffic is denied by default. You must explicitly allow traffic Learn More  ( 3 min )

What is LDAP and Why Do Ports Matter? LDAP (Lightweight Directory Access Protocol) is a widely-used protocol for accessing and managing directory information services over IP networks. At its core, LDAP relies on specific network ports to establish communication between clients and directory servers. Understanding these ports is crucial for network administrators, security professionals, and anyone working with directory services. An LDAP port is a communication endpoint that enables clients to connect to LDAP directory servers. These ports act as gateways through which LDAP queries, authentication requests, and directory operations are transmitted across networks. The port number tells the operating system which application or service should handle incoming network traffic. LDAP uses tw…  ( 5 min )

A Smart Contract Is Only as Useful as Its Deployment If you’ve ever written a smart contract, you might know that coding it isn’t the hardest part, especially if you’re already a smart contract developer. It’s the deployment phase—figuring out RPCs, managing wallet connections, compiling bytecode, dealing with testnets, gas settings, and contract verification—that tends to be a hassle. You end up combining a stack of CLI tools, browser extensions, config files, and maybe even a backend setup just to push one contract live. That’s why Kalp Instant Deployer (KID) was built: to turn contract deployment into something that feels as smooth and structured as deploying a microservice. In this post, we’ll walk you through how to use KID to deploy your first smart contract using Kalp Studio Conso…  ( 5 min )

What I Built, What I Broke, and What I Learned When I first heard the phrase “DOM Manipulation,” I thought it sounded like something out of a sci-fi movie. What I Built I created a simple social media-like interface where a user can: View a list of posts Click a button to “like” a post Add a new post using a form Delete a post (goodbye, cringey content!) It wasn’t Facebook or Instagram, but it was mine and it worked. Mostly. What I Learned JavaScript can actually make a page come alive. document.querySelector, addEventListener, and appendChild, the page started responding to clicks and input. That’s when it clicked—this is real programming. Mistakes are part of the journey. preventDefault() on my form submission, so the page kept reloading every time I added a post. It took me a while (and a few frustrated sighs) to realize what was wrong. But when I fixed it, I felt like a genius. Fetching data feels like magic. db.json file with a fake server and got to practice fetch() to get and display posts. At first, the promise syntax confused me. But once I broke it down and saw it work, it felt powerful. Beginner Tip If you’re just starting out, don’t worry about making it perfect. My code was messy. My console was full of red errors. But every single bug taught me something valuable. What’s Next I plan to revisit this project later and refactor my code, maybe even try to style it better with CSS. I also want to learn how to add images to posts and maybe store data in a real database. Final Thoughts This project taught me that learning to code is not about being perfect it’s about being curious and persistent. DOM manipulation isn’t scary anymore. It’s fun. And this is just the beginning. IT'S FUN.  ( 4 min )

Stop Building Frustrating SwiftUI Forms 🛑 Ever filled out a form that made you want to throw your phone? Poor focus management, aggressive validation, clunky transitions between fields? Yeah, we've all been there. Most iOS developers get forms wrong. Not because they're bad developers, but because SwiftUI's form components have hidden gotchas that can make or break the user experience. I just released a comprehensive SwiftUI forms tutorial that covers everything you need to build forms that users actually enjoy using: Smart TextFields with automatic focus transitions using @FocusState Picker components that make sense for your data (segmented, menu, navigation styles) Dynamic UI with Toggles and progressive disclosure patterns User-friendly validation that guides instead of punishes Modern @Observable pattern for complex form state management (iOS 17+) This isn't just theory. These are battle-tested patterns I use in production apps. The kind of forms that feel native, polished, and respect your users' time. We'll build everything from basic contact forms to complex user profiles with dynamic sections, proper keyboard handling, and validation that actually helps users succeed. I've also open-sourced the complete project with all 8 working examples: BasicFormView TextFieldExampleView FocusableFormView PickerExampleView DynamicToggleView ValidatedFormView UserProfileForm ImprovedFormView (with @Observable) Ready to build forms that don't suck? 👉 Watch the complete tutorial here The video walks through every pattern with live coding, explanations of the "why" behind each decision, and common pitfalls to avoid.

Node.js has many versions, and different projects may require different versions. To easily manage multiple versions of Node.js on Linux, we can use an npm package called n. To start using n, install the pacakge using the following command: npm install -g n If Node.js and npm are not installed yet, use the following command instead: curl -L https://bit.ly/n-install | bash Once installed, you can install and switch to a specific Node.js version using n . For example: n 16.17.1 # copying : node/16.17.1 # installed : v16.17.1 to /usr/local/bin/node # active : v16.17.1 at /usr/local/bin/node If you encounter an error like this: Error: EACCES: permission denied, symlink '/usr/local/n/versions/node/16.17.1/bin/node' -> '/usr/local/bin/node' You can solve this by setting the N_PREFIX environment variable in your .profile, .bashrc or .zshrc file (depending on your shell) to $HOME/.n. export N_PREFIX=$HOME/.n export PATH=$N_PREFIX/bin:$PATH Then, restart your shell or run the following command: source ~/.bashrc # depending on your shell Now, try installing it again: n 16.17.1 Once installation is complete, verify the current Node.js version: node -v # v16.17.1 To list all installed Node.js versions and switch to one of them, run the following command: n A list of installed Node.js versions will appear. Use the up/down arrow keys to highlight a version, Enter to activate it, d to delete it, and q to exit. For example: # node/14.21.3 # node/16.7.0 # node/16.17.0 # ο node/16.17.1 # node/22.11.0 # node/22.15.1 # node/22.16.0 To install the latest or LTS version of Node.js, use the latest or lts keywords. n latest n lts That's how to manage multiple Node.js versions on Linux.

The controversy raises important questions about privacy, technology, and political freedom. Catalonia's drive for independence has been a contentious issue in Spain, characterized by large demonstrations and political maneuvers to hold a referendum. However, the Spanish government deemed these moves unconstitutional, leading to a tense political standoff. At the heart of Catalangate is Pegasus, a sophisticated spywa…  ( 4 min )

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, Holistic Webdev: Office Space I went goofy and very literal for this one. Please don't take it super seriously, but I do want to provide some value to this article. The challenge was to create a home page within the themes of "office". So, I decided to attempt to create an actual office space (desk, wall, folders, etc.) and make IT the home page. I tried combining the art with the features (brand, navigation, upcoming events) as seamlessly as possible within the represented items inside the office (laptop, folders, desk, etc.). Disclaimer: I am not an artist so excuse the quality of the "drawings", but the idea is there... and hopefully you can see it. Also, I didn't make it responsive. Before showing you the…  ( 4 min )

Imagine EBS as the hard disk attached to our computer Key points to note down: Block-level storage (like HDD or SSD) Attached to a single EC2 instance at a time Stores all your system files, installed packages, project folders, .git, .ssh, etc. Persistent — our data stays even after instance shutdown (unless deleted manually) we're launching an EC2 instance to deploy a Flask app. we install Python, Docker, and some required libraries. All of this is stored in the EBS volume attached to our EC2. If we stop and restart the EC2, the data remains intact. Now we can think of EFS like a shared Google Drive. It's a network file system that multiple machines can connect to and use at the same time. Key points to note down: File-level storage (it save's ad folder and file structure as file explorer in windows) Can be mounted on multiple EC2 instances simultaneously Accessible over a network (NFS-Network File System) Automatically scales as we store more data Like we're part of a team using multiple EC2 instances to work on a shared dataset. we store that data in EFS, so everyone’s EC2 can read and write to it at the same time — like a shared workspace. Table Comparison from Chat-GPT: EBS → Like your personal hard disk EFS → Like a shared Google Drive folder for your team If this helped you understand EBS vs EFS better, drop a ❤️ and let me know your thoughts in the comments.

Why optimizing images from a beach café in Bali taught me more about web performance than any conference ever could I'm writing this from a 50-year-old coffee shop in the mountains of Colombia, where the WiFi speed is 2.3 Mbps on a good day and electricity comes and goes like an old friend. Three months ago, I was a Silicon Valley developer optimizing images for users I'd never met on connections I'd never experienced. Today, I'm one of those users—and everything I thought I knew about image optimization was wrong. This is the story of how becoming a digital nomad transformed my understanding of image optimization from theoretical exercise to daily survival skill. // My optimization assumptions vs nomadic reality const realityCheck = { // My Silicon Valley assumptions siliconValleyAssu…  ( 11 min )

GitHub Homepage As a junior computer science student, I have encountered various frameworks during my web development learning journey. From traditional Apache to modern Node.js, each framework has its unique advantages and limitations. Recently, I discovered an impressive Rust web framework whose performance made me reconsider the design philosophy of web servers. Throughout my learning experience, I found that traditional web frameworks often face performance bottleneck issues. Taking Apache as an example, while it is powerful and stable, its performance in high-concurrency scenarios is not ideal. I once conducted a simple performance test where Apache's average response time for 10,000 requests reached 300 microseconds, and in some complex scenarios, it even exceeded 2,500 microseconds.…  ( 6 min )

When you compress an image, is it still the same image? A journey through the unexpected philosophy of digital optimization Last Tuesday, I spent three hours optimizing a photograph of my daughter's first steps. The original file was 4.2MB. The optimized version was 127KB—a 97% reduction. Both images looked identical to my eyes, but every single pixel had been mathematically transformed. Not one byte remained unchanged from the original. Which one was the "real" photograph of my daughter's first steps? This question sent me spiraling into the unexpected philosophical depths of image optimization. What started as a technical task became an exploration of identity, authenticity, and the nature of digital reality itself. Image optimization, it turns out, forces us to confront some of the deep…  ( 11 min )

SQL Server backup: Problem: Today, the SQL backups are being storged in backup volume or in similar place in same EC2 server. First this doesnt help for recovery and Second this leads to duplication of storage as AWS Snapshots take backup of backup. Solution: Use storage gateway to offload the backups to reduce the local EBS storage being used by backups. The gateway can be implemented in 2 ways, 1-In a OU (group of aws accounts) to share between various account to save gateway device cost or 2-In each aws account if there is a business need or it there is too-much data being traversed over VPC's AWS Opensearch GP2 Storage: (to be explored) Problem: All of the Opensearch nodes use legacy GP2 storage. This costs bit more and only offers thru put based on the volume. i.e using lower disk space might lead to lower thru put, this might be compensated by using higher spec instance sizes. Solution: Use GP3 storage with varing thru put based on the domain. Initially, achieving a right thru put might be a challenge, but we will gain in long run. AWS Opensearch Warm/cold storage: (to be explored) Problem: Today all of the storage in Opensearch is Hot storage. This means we are paying more for storage whether we use it or not. Solution: The application can index the data by warm, cold and there by offloading the cold storage to s3 bucket there by saving cost on hot storage of EBS. Lamba tuning: (to be poc'd) Lambda tuning allows to fine tune the memory parameter by doing performance testing various parameters. This gives a picuture of sweet sport configuration based on various configuration. We could try out most used lambda's using AWS proposed Lambda tuning process and see if we can get savings out of it.  ( 3 min )

1. Why Go Concurrency Matters (and Why You Should Care) Concurrency isn’t just a buzzword—it’s the backbone of modern backend dev. Picture this: your API’s juggling thousands of requests, or your data pipeline’s chewing through logs faster than you can say "multithreading." Go’s goroutines and channels swoop in like superheroes, making concurrent programming feel less like a chore and more like a superpower. Goroutines are like tiny, tireless workers; channels are the slick pipes passing data between them. Simple, elegant, and oh-so-powerful. I’ve been slinging Go code for over a decade—think APIs, task schedulers, the works—and I’ve seen Go shine in high-pressure scenarios. But I’ve also tripped over my share of gotchas (goroutine leaks, anyone?). This guide’s for devs with a year or tw…  ( 12 min )
